# Soft Cloud-Layer Diagnostic Narrative · PPT Design System (brand-free, reusable version)
This document is reverse-engineered from a 32-page technical talk source deck, retaining only the visual language and narrative method for reuse in any technical-proposal-style presentation. The full text contains no third-party logos, brand names, people, product screenshots, source-deck body text, or original data; any value that could not be precisely sampled is marked "approximate."
Applicable scenarios: performance diagnostics, monitoring proposals, technical methodology talks — narrative-style presentations that follow "pose the problem → establish metrics → give the method → show evidence → close the loop."
## Visual DNA
- Primary tone: **white background + bold dark-blue titles + a single accent color bar**. Pages have abundant whitespace, low-to-medium information density, one point per page.
- Character keywords: clean, restrained, soft, engineering-feel. All decoration serves the narrative — decoration is never added for its own sake.
- Two cover moods:
- The opening cover uses a **soft pink-purple cloud-layer gradient** (approximately `#F7CDD8` → `#DCC8F2`), creating a light, friendly first impression.
- The closing page uses a **deep-purple gradient** (approximately `#3A1D6E` → `#5C40A8`) with large white text, closing out the whole talk.
- Recurring identity element: a **short, thick underline** below and to the left of the title (about the width of the title's first word, about 4–6px tall), whose color switches with the current section's theme color (a yellow-green or bright-yellow family). This is the entire deck's only "brand anchor" and may be replaced with any theme color.
- On-page emphasis relies on **font weight and bolded keywords**, occasionally seasoned with a single emoji (at most one per page); icon-stacking is not used.
## Canvas and Grid
- Aspect ratio: **16:9** (1280×720 or equivalent), landscape projection preferred.
- Safe margins (approximate): about 5% on left and right each (≈64px @1280), about 6% at the top, about 8% at the bottom (footer zone).
- Grid: an implicit 12-column grid. Body text defaults to a left-aligned single column, occupying the left 7–8 columns; image-text pages commonly use a "text left, image right" 7:5 split, or a centered large image spanning 10 columns.
- Baseline rule: titles consistently start from the same y-coordinate (approximately 8–10% from the top); the body's starting point is consistently about 48–64px below the title underline, with no drift across the deck.
- Bottom diagonal color band: some section pages place a **large-angle diagonal color band** at the bottom edge or lower right (height about 15–25% of the canvas, diagonal angle about 5–10°) as a visual signal for section separation; content pages usually stay pure white.
## Font Hierarchy
Font family: Liter (English) and MiSans (Chinese), approximating a system sans-serif; use JetBrains Mono (via customFonts) for code and other monospace needs. Do not use serif or other decorative fonts.
| Tier | Purpose | Font size (approximate, 1280-width baseline) | Weight | Color |
|---|---|---|---|---|
| H1 page title | The single title per page | 34–40px | Bold | Deep-blue ink |
| Cover main title | Opening cover | 40–48px | Bold | Deep purple |
| Cover subtitle | Byline/date line | 20–24px | Italic/Regular | Deep purple (lighter) |
| Subheading/definition question | "What is X?"-style lead-in sentence | 18–22px | Bold | Deep-blue ink |
| Body/list | Points, paragraphs | 16–18px | Regular, keywords Bold | Dark gray |
| Annotation/footer | Copyright, source, small print | 10–12px | Regular | Medium gray |
Rules:
- Titles are mostly **questions or assertive statements** (e.g., "What are our goals?", "Context is everything"), advancing the narrative directly through the title.
- Body emphasis uses inline Bold, not color changes or underlines.
- Definition pages follow a fixed sentence pattern: a subheading question + a definition paragraph (keywords bolded) + one "goal sentence" summarizing the experience goal that metric corresponds to.
## Color Tokens
The following are reverse-sampled approximate values; fine-tune on implementation, but maintain the relationship of "a low-saturation base color + one high-saturation accent color."
- `--ink` (titles/emphasized text): deep-blue ink, approximately `#1C2B4A`
- `--body` (body text): dark gray, approximately `#333A45`
- `--muted` (annotations/footer): medium gray, approximately `#8A93A0`
- `--paper` (base color): pure white `#FFFFFF`
- `--accent-lime` (theme accent A, green-family sections): approximately `#8CC63F`, used for title underlines, diagonal color bands, and loop diagrams
- `--accent-yellow` (theme accent B, yellow-family sections): approximately `#F2A900`, used for title underlines, diagonal color bands, and task bars
- `--cover-gradient`: pink `#F7CDD8` → pale purple `#DCC8F2` (cover cloud-layer base)
- `--end-gradient`: deep purple `#3A1D6E` → purple `#5C40A8` (closing-page base)
- `--purple-title` (cover title): approximately `#6E2E7E`
- Three-state status colors (rating/threshold legend, approximate): `--ok` `#3FBF6F`, `--warn` `#F5C400`, `--bad` `#F05A5A`
- Timeline bar colors (approximate): task segment `--task` `#F5D76E`, event segment `--event` `#B98FE0`
Usage constraint: each page has **one and only one** accent color (green-family or yellow-family, determined by the section); the three-state status colors appear only grouped within rating legends and are not mixed with the section accent color for decoration.
## Page Skeleton
The whole deck is organized around a "diagnostic narrative arc," with a reusable skeleton sequence:
1. **Cover**: gradient cloud-layer base + left-aligned main title/subtitle, with a slot at the upper right for an event or institution mark (leave blank when reusing, or place your own mark).
2. **Quote page**: pure white background, an oversized quotation-mark character (theme color) + a quote paragraph + an em-dash byline, with a diagonal color band at the bottom. Used to establish thematic authority.
3. **Goals page**: a question-style title + a bullet list of up to 4 items, answering "what are we pursuing."
4. **Section title page**: pure white or with a diagonal color band, a large short-phrase title (e.g., "Common metrics"), serving as a section divider.
5. **Metric definition pages** (repeated in groups, 1–3 pages per metric):
- Definition page: a question-style subheading + a bolded-keyword definition + a goal sentence.
- Problem page: a "Some issues with X"-style list of limitations.
- Calculation/measurement page: a formula or diagram + a wireframe illustration such as a phone outline.
6. **Method turning-point page**: a large-text question (e.g., "So… what should we measure?") + one witty answer line, picking up from the first half's setup.
7. **Context/method page**: a checklist-style question ("Do we care about…?"), pulling absolute metrics back to a concrete scenario.
8. **Implementation page**: text-left/code-right, full-width code, or a step list, explaining the means of implementation.
9. **Evidence page**: a timeline diagram, Before/After comparison, or rating bar, presenting the measurement results.
10. **Closed-loop page**: a loop diagram (Measure → Analyze → Improve), making the point of a "continuous process."
11. **Recap page**: a "Recap" summary of 5–6 bolded-keyword points.
12. **Closing page**: deep-purple gradient + large white "Questions?"-style text.
## Reusable Layouts
- **L1 pure list page**: title + underline + bullet list (≤6 items, each within one and a half lines). Applicable to: goals, limitations, summaries.
- **L2 text-left/image-right page**: 40% text on the left (definition/list), 60% large image or diagram on the right. Applicable to: concept explained with an illustrative screenshot-style diagram, code explanation.
- **L3 centered large-image page**: title on top, a centered image below spanning 60–80% of the width (timeline diagram, waterfall chart, curve chart). Applicable to: evidence presentation.
- **L4 comparison page**: two groups of matching wireframe diagrams (e.g., phone wireframes, task bars) arranged left-right or top-bottom, connected by a middle arrow, labeled Before / After. Applicable to: before/after optimization, two alternative solutions.
- **L5 formula page**: title + a centered formula line + an illustrative example below + one line of calculation result. Applicable to: metric algorithms.
- **L6 quote/question page**: a single large-text sentence, centered or left-offset, paired with a theme-color symbol (quotation mark, ellipsis). Applicable to: transitions and tone-setting.
- **L7 code page**: title + a dark rounded-corner code block (positioned right or full-width), with 2–4 lines of explanation on the left. Syntax highlighting within the code block uses a soft color scheme, not a pure-black background (approximately deep charcoal-gray `#2B2F38`).
- **L8 loop-diagram page**: a centered ring/loop-arrow diagram (3 nodes: Measure, Analyze, Improve), with one sentence at the ring's center. Applicable to: methodology closed-loop.
## Chart/Table/Image/Component Rules
- **Timeline/waterfall chart**: horizontal bands express stage duration, with stages distinguished by soft fill colors (yellow = task, purple = event, approximate), thin leader lines connecting to stage-name labels; the vertical or horizontal axis retains only necessary tick marks.
- **Before/After task bars**: two horizontal bars — the top row "before optimization" as one long bar, the bottom row "after optimization" split into several short bars, with arrows marking event-handling points; colors as above.
- **Rating-bar component**: a large metric abbreviation (theme color or deep blue) + three color bars below (green/yellow/red) labeling Good / Needs Improvement / Poor and their thresholds, with three placed side by side for comparison. When reusing, replace with any three-tier rating semantics.
- **Wireframe device illustration**: use a simple rounded-rectangle wireframe to represent a phone/browser viewport, with only gray block placeholders inside to express content layout, and red/blue dashed lines and arrows marking displacement or regions; **do not embed real product screenshots**.
- **Curve chart**: a single smooth curve + sparse axes (a three-tier scale like 0%/50%/100%), no gridlines, mostly whitespace.
- **Loop diagram**: a ring divided into three equal arrow segments, node words arranged along the outside of the ring, a short sentence at the ring's center, arrows using a theme-green gradient.
- **Tables**: the whole deck almost never uses data tables; if one is needed, use a minimalist style with no vertical rules, thin dividers between rows, and a bolded, background-free header.
- **Images**: always placed centered with a thin gray border or no border; using third-party product-interface screenshots, real website photos, or photos of people is prohibited.
- **List symbols**: dots are the default; "recommended/satisfied"-type lists may use a green checkmark (✅) instead of a dot.
## Density and Spacing
- **One core message per page**: the title is the conclusion, and the body only supports that conclusion.
- List-page body text does not exceed 6 items; definition-page body text does not exceed 120 words; code-page code does not exceed 25 visible lines.
- Paragraph spacing (approximate): title underline → body text 48–64px; between list items 12–16px; image → caption text 24–32px.
- Whitespace ratio: on pure-white content pages, the effective content area occupies about 50–65% of the canvas, with the rest as whitespace; prefer splitting across pages over compressing line spacing.
- Overall page-count rhythm reference (32 pages): setup 40% (goals + metric definitions), turning point 10%, method and evidence 35%, closing 15%.
## Footer and Page Numbers
- Footer position: lower-left corner, a single line of 10–12px medium-gray small text (approximate), containing a copyright line like "© Year Institution Name. All rights reserved."; replace with your own institution when reusing, or remove it.
- A **small mark slot** may be placed on the left side of the footer (approximately a 16×16px colored-dot/graphic placeholder); when reusing, place your own logo or leave it blank — do not reuse the source deck's mark.
- The source deck **does not display page numbers explicitly**; if page numbers are needed, a medium-gray number at the lower right in 10px is recommended, on the same baseline as the footer.
- The cover and closing gradient pages carry no footer or page number.
## Prohibited Items
- Do not copy any third-party logo, conference mark, brand name, trademark, or mascot graphic.
- Do not use real product/website screenshots, real data, or the original charts and specific values from the source deck.
- Do not quote sentences from the source deck's body text; definitions and copy must be rewritten following this system's sentence patterns.
- Do not include photos of people or a speaker's likeness.
- Do not mix multiple decorative colors: each page is limited to one section accent color for decoration (except the three-state status legend).
- Do not use shadows, gradient text, outlined large text, 3D effects, or complex textured backgrounds (except the specified gradients on the cover and closing pages).
- Do not use serif or handwriting fonts, and do not introduce decorative variants beyond the specified Regular/Bold weights and limited italic usage.
- Do not add a large color-block background on pure-white content pages; color blocks are allowed only in the bottom diagonal band, the title underline, and inside charts.
## Delivery Checklist
- [ ] 16:9 aspect ratio, with margins and title baseline consistent throughout.
- [ ] Each page has only one title and one core message; the title is a question or an assertive statement.
- [ ] The title underline is present and its color matches the current section's accent color.
- [ ] The entire deck uses only the font size/weight/color combinations from the font hierarchy table.
- [ ] The section order follows the "problem → metrics → turning point → method → evidence → closed loop → recap → closing" skeleton.
- [ ] Metric-related content uses the "definition page + limitations page + calculation/evidence page" grouped structure.
- [ ] At least one Before/After comparison page and one closed-loop diagram page are included.
- [ ] Chart colors are drawn from the tokens, with no extra decorative colors outside the charts.
- [ ] The cover is a soft pink-purple cloud-layer gradient; the closing page is a deep-purple gradient + large white text.
- [ ] The footer copyright line has been replaced with your own institution or removed; no source-deck marks remain; page-number style is compliant.
- [ ] The document contains no third-party brands, screenshots, people, original text, or original data; approximate values have been calibrated to actual needs.
- [ ] Pure-white pages retain ≥35% whitespace, with no crowded pagination; code line counts and list-item counts stay within the limits.
- No cards by default: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment: lines, whitespace, and font-size differences are the superior solution
- No evenly-divided composition: unless there is no other usable layout, do not default to three-way splits, four-way splits, or 2×2 matrices. This includes three-part conclusions such as three-column + title + conclusion

# Academic Thesis Defense Design System (brand-free, reusable)
> Applicable scenarios: long academic thesis defenses / research presentations / paper talks (100+ page scale). This system abstracts only visual and layout rules and contains no brand, person, institution, title, original text, original figure, or real data.
---
## 1. Visual DNA
- **Character**: restrained, academic, white-background minimalism. Information density is high but whitespace is generous, winning through typographic hierarchy rather than decoration.
- **Base color**: a pure white canvas, with full-bleed color blocks appearing very rarely; color is used only as functional coding (emphasis, categorization, progress), never as decoration.
- **Line quality**: core illustrations use a hand-drawn/line-art style (thin black lines, gray fills), contrasting with the sans-serif body font to create a "rigorous framework + approachable diagram" feel.
- **Progressive narrative**: the same composition is built up progressively across multiple pages (frame-by-frame highlighting, graying-out, adding elements) — this is the deck's single most important expressive device, so static pages must reserve room for "step-by-step reveal."
- **Dual-engine structure**: main-thread sections are driven by a full-width navigation footer; side-thread/backup slides (extra slides) use a simplified footer, with one stable page skeleton unifying 140+ pages.
## 2. Canvas and Grid
- **Ratio**: 16:9 landscape.
- **Safe margins**: about 4–5% of the canvas width on left and right, about 6% at the top, with about 10–12% reserved at the bottom for the footer zone.
- **Main grid**: mostly a single column; for two-column comparisons, equal widths on both sides (48/48, with a 4% gap in between); for a four-column card grid, four equal-width columns with consistent column gaps.
- **Alignment**: titles, body text, and charts are all left-aligned; only cover secondary info, divider-page large text, and the acknowledgments page may be centered or center-left.
- **Content area**: title area (top, one line) + body area (middle, about 70% of the height) + footer area (a fixed band at the bottom). Within the body area, when charts and text are mixed, text sits on the left and diagrams on the right or center.
## 3. Font Hierarchy
The whole deck uses a single sans-serif family, QuattrocentoSans (humanist sans; Chinese: MiSans), differentiated only by weight and size; code/formula snippets use JetBrains Mono (brought in via customFonts).
| Tier | Purpose | Relative size | Weight | Color |
| --- | --- | --- | --- | --- |
| H0 | Cover main title | 100% baseline ×2.2 | Bold | Near-black |
| H1 | Content-page title | ×1.5 | Bold | Near-black |
| H2 | Column title / card title | ×1.1 | Bold | Near-black |
| Divider-page large text | Section divider page | ×1.8 | Bold (keywords) + Regular (the rest, light gray) | Black/light-gray mix |
| Body | Lists and paragraphs | ×0.85 | Regular | Near-black |
| Small text | Footnotes, table notes, figure captions | ×0.6 | Regular | Medium gray |
| Footer | Navigation and page number | ×0.5 | Regular (current item Bold) | Gray/black |
- Body line height 1.3–1.4; list-item spacing is 0.5× the line height.
- Emphasis is limited to: **bold**, the theme color, and a local highlight background — italics, underlines, and shadowed text are not used.
## 4. Color Tokens
| Token | Color value (approximate) | Purpose |
| --- | --- | --- |
| `bg` | `#FFFFFF` | Global base color |
| `ink` | `#1A1A1A` | Titles and body text |
| `ink-muted` | `#8C8C8C` | Secondary text, non-current footer items, grayed-out state |
| `line` | `#BFBFBF` | Table rules, connecting lines, chart axis lines |
| `accent` (primary) | `#2E8B7E` deep teal-green | List square markers, divider-page outline, quote/label block background |
| `accent-wash` | `#DFF1EE` | Light background for label blocks |
| `info` (secondary) | `#5B9BD5` medium blue | Goal/conclusion banners, card headers, icon background |
| `info-wash` | `#E8F1FA` | Light fill for banners and card bodies |
| `highlight` | `#F2B90F` amber | "Current focus" highlight during progressive builds, key values, local background |
| `annotate` | `#8E5AA8` purple | Annotation bubbles, quotation-marker boxes |
| `danger` | `#C0504D` red | Negation, error paths, cancellation marks (used very sparingly) |
| `neutral-tag` | `#9AA5B1` | Secondary group bar (e.g. a "baseline/gap" group header) |
Rules: colored area per page ≤ 15%; the same semantic meaning stays the same color throughout the deck (e.g. "in progress/focus" is always amber); graying-out is the only way to express "past/irrelevant."
## 5. Page Skeleton (Masters)
1. **Cover page**: a title block at upper left (main title Bold + subtitle + one small line of byline/date); below, a full-width dark banner image occupying about 1/4 of the height (abstract texture, not a photo of people).
2. **Section divider page A (gray-text style)**: a large title centered-left, with non-keyword portions in light-gray Regular and keywords in black Bold, creating "light/dark contrast within one sentence."
3. **Section divider page B (outlined-frame style)**: a thin-lined rounded rectangle centered on the page (`accent` outline, no fill), with the section name centered inside in Bold; even whitespace above and below.
4. **Standard content page**: H1 at upper left; the body area carries a list/two columns/chart/table; a fixed footer at the bottom (see §9).
5. **Section summary page (Digest)**: H1 reads "Section Name - Digest"; the left side is a three-part structured list (Task / Method / Result, each with 2–4 square-marker sub-items), the right side has one method diagram + 1–2 source label blocks (`accent-wash` background + `accent` text + a small icon).
6. **Conclusion/closing page**: reuses the standard content page, with list items allowed to end with a back-reference mark such as "→ Goal number ✓" (circle + number + checkmark).
7. **Acknowledgments page**: purely text, centered, two lines (a main sentence + a secondary sentence), optionally paired with a simple symbol.
8. **References page**: H1 + a two-column or single-column dense numbered small-text list (×0.55 size), with no other decoration.
9. **Backup/appendix pages**: share the same skeleton as the main content, but the footer switches to simplified navigation (only 3–4 groups + a dot-progress indicator).
## 6. Reusable Layouts
- **L1 single-column list**: H1 + a multi-level square-marker list, up to three levels; level 1 uses a solid `accent` square, level 2 a small square or short dash of the same color, level 3 hollow/gray.
- **L2 two-column comparison**: two equal-width columns, with a Bold short phrase as the column header ("A looks for … / B looks for …" pattern), each column containing a short list; no divider line is drawn between them — grouping relies on spacing.
- **L3 centered pithy statement**: a bold statement line at the page's center (which may include a symbol like ⇒), with large whitespace above and below; used for transitional argument pages.
- **L4 banner card**: `info-wash` background + a solid `info` icon area on the left + a Bold label on the right + one line of explanation; rounded corners, thin border; used for statements that "need to be remembered," such as research goals or core conclusions.
- **L5 multi-column goal matrix**: a rounded `info` header bar at the top (with a gear-type icon on the left) → a `neutral-tag` group header below it (two groups: baseline / gap) → 4 equal-width columns, with column headers as rounded `info` chips (number + short name) and column bodies as `info-wash`-filled rounded rectangles; a vertical sidebar at the far left, embedding 4–6 line icons + vertically arranged category text. Matrix cells support three fill states: empty (yet to be discussed) / a ✓✗ comparison grid / numbered points + source labels.
- **L6 progressive-build page**: the same composition spans multiple consecutive pages, with each page adding only one change: ① a new element fades in; ② an existing element is emphasized with a `highlight` yellow frame/background; ③ non-focus elements are grayed out as a whole (`ink-muted`). The page must be designed as a composition stable enough that "adding one more layer still doesn't collapse it."
- **L7 text-left/image-right**: a structured list on the left, a line-art diagram on the right (document icons, connecting lines, label chips); the image occupies about 45% of the width.
- **L8 full-width table/figure**: H1 + a table or chart occupying 90% of the body area, with small-text footnotes immediately following.
- **L9 large comparison table**: a multi-row, multi-column metric comparison table + one line of small footnote text at the bottom explaining the measurement basis.
## 7. Chart / Table / Image / Component Rules
**Charts**
- Style: academic simple diagrams. Thin gray axis lines, no decorative tick marks, direct labeling; bars, lines, and scatter plots are all usable, with colors limited to `accent`, `info`, `highlight` + two shades of gray.
- Error bars and confidence intervals are expressed with thin lines; legends sit at the upper right or right side inside the chart, at ×0.6 size.
- When multiple subplots sit side by side, unify the axis range and font size; subplot labels use small (a)(b)(c) markers.
- Time/trend line charts may use multiple thin colored lines, but the same metric must use the same color across pages.
**Tables**
- A three-line-table variant: a medium-thin horizontal line at the top and bottom, a thin horizontal line below the header, with no vertical lines or only extremely faint vertical lines.
- Headers are Bold, numbers are right-aligned or aligned by decimal point; the best value may be Bold + colored with `accent`, but at most once per column.
- Table footnotes: a superscript letter/symbol + ×0.55 gray text, immediately following the table.
**Images and diagrams**
- Only two types are used: ① an abstract full-width banner (cover-only); ② a line-art diagram (document/pipeline/process). Photos, screenshots, and realistic illustrations are prohibited.
- Line-art diagram convention: thin black outlines, gray-scale fills simulating lines of text, small colored chips marking key positions; elements are connected by gray curved arrows, with arrows indicating direction only, not weight.
- Icons: a unified set of line icons (same stroke width, same corner radius), in two sizes (within lists / within cards), colored from `accent`/`info`/gray.
**Components**
- Square-marker list: a solid small square ■, in `accent` color, sized at about 0.45× the text height.
- Source/citation label block: a rounded rectangle, `accent-wash` background + `accent` text, with a small document icon on the left; 1–2 may appear side by side on the same page.
- Annotation bubble: a rounded rectangle + a pointer line, `annotate` outline, containing a handwriting-feel short sentence or formula fragment inside; used only for "in-text quote/parameter"-type annotations.
- Numbered back-reference: circled numbers (①②③) used for point numbering; goal back-references use "diamond/circle + number + ✓."
- Pipeline diagram: left-to-right flow, with stages represented by line-art blocks or cylinders (data sources) + rectangles (artifacts), stage numbers placed on gray rounded bars, arrows as solid gray lines.
## 8. Density and Spacing
- **Rhythm**: content pages have medium-to-high information density (1 central argument per page + ≤ 6 first-level points); insert one low-density divider or pithy-statement page every 8–15 pages as a breathing point.
- **Spacing system** (with body text size as 1u): title to body 1.5u; between list items 0.5u; between list groups 1u; chart to caption 0.75u; between columns 2u; footer to body 1.5u.
- **Progressive-page discipline**: each step of a step-by-step reveal changes only one thing; do not add a new element and gray out another within the same step.
- **Whitespace floor**: on any page, the bounding box of the body area's elements must not exceed 85% of the content area, and at least two corners must retain noticeable empty space.
## 9. Footer and Page Numbers
- **Main-thread footer (three parts)**:
1. Top navigation row: all section names laid out horizontally (about 7–8 items), with the current section Bold near-black and the rest `ink-muted`; below each section name is a row of small dots representing that section's page count — discussed/current dots are solid (the current page's dot in `accent` or solid black), undiscussed dots are hollow.
2. Lower left: a small `current page/total pages` label (e.g. `12/51` or as a fraction).
3. Bottom row: a date (left) + a gray small-text byline row (speaker · report title, replaced with a generic placeholder when reusing).
- **Backup-page footer**: only 3–4 group names + a dot-progress indicator + page number, with no byline row.
- Divider page B and the acknowledgments page may omit the footer entirely; divider page A retains the footer to maintain a sense of position.
- Page numbers are numbered continuously throughout the deck (the backup section may either restart or continue the numbering, as long as the choice is applied consistently).
## 10. Prohibited Items
- Prohibited: any brand mark, institutional logo, real person's name/photo, the thesis's original title and body paragraphs, original charts and real experimental data, webpage/software screenshots, or original reference-list entries.
- Prohibited: gradient fills, drop shadows, 3D effects, decorative display type, textured backgrounds, full-bleed colored background pages.
- Prohibited: italics/underlines as emphasis, more than two colors emphasizing the same element simultaneously, sticker-style emoji graphics.
- Prohibited: vertical body text (only sidebar category labels may be set vertically), list nesting beyond three levels, more than one central argument per page.
- Prohibited: footer dots not matching the actual section page count, the same semantic color changing across pages, and jumpy positioning across progressive-build pages.
## 11. Delivery Checklist
- [ ] 16:9, white background; no brand, no people, no photos/screenshots, no original text/figures/data.
- [ ] Only one sans-serif family + one monospace font are used; font-size tiers match the §3 table.
- [ ] All colors come from the §4 tokens; colored area per page ≤ 15%; the same semantic meaning uses the same color.
- [ ] All eight reusable skeletons — cover, the two divider-page types, standard content page, Digest page, conclusion page, acknowledgments page, references page, backup page — are present and reusable.
- [ ] At least one example each of layouts L1–L9; progressive-build pages change only one thing per step and keep a stable composition.
- [ ] Tables follow the three-line-table style with complete footnotes; chart colors are compliant, with the same metric using the same color across pages.
- [ ] The footer's navigation section names + dot progress match the actual state; page numbers are continuous; the backup section's footer is the simplified version.
- [ ] The four component types — square-marker lists, source label blocks, annotation bubbles, numbered back-references — are styled consistently throughout the deck.
- [ ] A low-density breathing page appears every 8–15 pages; the body area occupies ≤ 85%.
- [ ] The whole document is UTF-8; placeholder text uses generic research narrative (goal/gap/task/method/result/limitation) with no identifiable source information.
- No cards by default: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment: lines, whitespace, and font-size differences are the superior solution
- No evenly-divided composition: unless there is no other usable layout, do not default to three-way splits, four-way splits, or 2×2 matrices. This includes three-part conclusions such as three-column + title + conclusion

A brand-free design system for math/ML-style deep-dive tutorials: pastel-gradient section covers + white-background derivation content pages, with "contour probability plots + formula cards + progressive reveal" as the core narrative device. This system abstracts only the visual style and pacing of explanation, and contains no brand, person, original text, or original chart.
## 1. Visual DNA
- **Two page skins**: ceremonial pages (cover, agenda, section dividers, back cover) use a diagonal pastel gradient; content pages use a near-white solid color, with high information density but generous whitespace.
- **Warm-toned figure area**: all probability/geometry diagrams sit on a uniform warm off-white (peach) canvas block, with orange-to-deep-red heat contour lines representing density — a recurring visual anchor throughout the deck.
- **The formula is the protagonist**: a large serif italic formula, centered or occupying its own line, carried by a pale blue-gray rounded "formula card"; within body text, key terms are colored blue (process/link), magenta (warning/key point), or teal (condition/input) rather than piled up with bold.
- **Progressive reveal (build-up)**: the same title is reused across consecutive pages, adding elements frame by frame and fading in the next conclusion; the pacing is one concept per page, breaking the derivation down as slowly as possible.
- **Rounded-pill components**: definitions, theorems, goals, and caveats are all placed inside rounded rectangles/pill bars, in a two-part "label + content" structure.
- **Annotation arrows**: thin blue/magenta arrows with text labels point to a specific term in a formula or a region of a diagram, replacing parenthetical notes.
- **Small-print footnotes**: a line of extremely small gray text at the bottom of the page carries sources/supplementary notes; body text never cites a reference number.
## 2. Canvas and Grid
- Aspect ratio: 16:9, recommended 1280×720 pt (or 33.87×19.05 cm).
- Safe margins: 48 pt left/right, 40 pt top/bottom; the footer band sits 12 pt above the bottom edge.
- Content grid: 12 columns, 16 pt column gap; common placements are 4+8 (text left, image right), 6+6 (two-column comparison), 3×4 (three-card row), and full-width (single image/single formula).
- Title anchor: upper-left corner, x=48, y=40, title block 72 pt tall, with the content area starting 24 pt below it; the content area's bottom ends at y=640, leaving room for the footnote below.
- Figure-area alignment: all diagram canvas blocks use a unified set of width/height sizes (e.g. 320×240 / 480×360 / full-width 600×420); sizes are not mixed within the same section.
## 3. Font Hierarchy
| Tier | Font | Size | Color | Purpose |
| --- | --- | --- | --- | --- |
| H1 cover/divider title | Sans-serif (e.g. Inter/Helvetica Neue) Medium | 40–48 | Ink black | Main title, section name |
| Section number | Sans-serif Light | 40 | Ink black 70% | Large "01"-style numbering |
| H2 content-page title | Sans-serif Medium | 28–32 | Ink black | Each page's upper-left title |
| Subtitle/pill small title | Sans-serif Medium | 14–16 | Primary blue or ink black 70% | Card labels |
| Body/bullets | Sans-serif Regular | 16–18 | Ink black 85% | Lists, explanations |
| Formulas | Serif italic (CMR/Times family) | 18–28 (protagonist formulas larger) | Ink black, key terms colored | Derivations, theorems |
| Colored keywords | Same as body | Same as body | Blue/magenta/teal | Inline emphasis, replacing underlines |
| Figure captions/footnotes/sources | Sans-serif Italic | 9–11 | Gray 60% | Footer line, figure captions |
| Table text | Sans-serif | 12–14 | Ink black 85% | Comparison tables, data tables |
## 4. Color Tokens
- `--ink` `#1F1F24` (primary text); `--ink-70` `#5A5A63`; `--muted` `#8A8A94` (footnotes/captions).
- Primary accents: `--blue` `#2E6FD6` (process, link, "generate/derive" semantics); `--magenta` `#C8366E` (warning, caveat, key assumption); `--teal` `#0E8A8F` (condition, input, example label).
- Ceremonial gradient color (diagonal 135°, four equidistant stops): `#F7D3E4` (pink) → `#E3DCF7` (lavender) → `#CDE4F6` (sky blue) → `#D7F2E6` (mint). Used as a full-bleed base only on ceremonial pages; prohibited on content pages.
- Figure-area base: `--peach` `#FCEFD9`; density heatmap: `#F2A65A` → `#E0743C` → `#B23A30` (light orange to deep red, 4–6 contour tiers, 0.75–1 pt line width, with a darker outline of the same hue).
- Component background: `--pill` `#EDF2F9` (pale blue-gray info card); `--note` `#FFF7CC` (pale yellow tip bar); `--caveat-bg` `#F3EEF1` (warning-bar background).
- Structural gray: divider lines `#D8D8DE`, table alternating-row background `#F5F6F8`.
- No more than 3 color tokens are used as emphasis on a single page; text coloring follows the fixed semantics of "blue = process/reference, magenta = limitation/problem, teal = condition/example."
## 5. Page Skeleton
1. **Cover**: gradient background; main title + one subtitle line at center-left; a QR-code slot at lower right (replace with your own link or remove when reusing); an info bar at the bottom (institution/date/license-icon slot).
2. **Agenda page**: gradient background; "H1 Agenda" on the left, vertical entries on the right in the form `[Duration] NN Section Name`, with the number in primary blue and the duration in muted gray.
3. **Section divider page**: gradient background; a large number (01/02/…) on the left in the same row as the section name; an optional QR-code slot on the right.
4. **Content derivation page**: white background; H2 title at upper left; content area placed per the grid; a footnote line at the bottom.
5. **Topic-switch page (progress-bar style)**: white background; 2–3 rounded thumbnail cards in a row, the current topic in normal color and the rest grayed to 30%, previewing/reviewing the section structure.
6. **References page**: white background; grouped subheadings + two groups of pale blue-gray rounded cards, each card containing a small italic citation list.
7. **Back cover**: gradient background; a large centered rounded functional card (a list of supported capabilities + a repository/link QR-code slot).
## 6. Reusable Layouts
- **L1 concept diagram**: 5 columns of text on the left (definition + bullet list, dot markers), 7 columns of peach figure canvas on the right; an optional line of small teal annotation below the figure.
- **L2 formula protagonist**: a full-width centered formula (serif, 24–28), a pill-shaped conclusion line above, and a pale blue-gray card below stating "conditions for validity/equivalent relations"; within the formula, different terms are colored blue/magenta with arrow labels attached.
- **L3 two-column comparison**: two side-by-side rounded gray cards, each containing a small thumbnail + 3–4 lines of bullet points (one column of "simple/fast/precise"-type advantages, one column of "large design space/slow"-type costs), with a shared symbol optionally sandwiched between them.
- **L4 three-topic navigation**: three thumbnail cards in a row with the current one highlighted (used for switching between sub-sections within a chapter).
- **L5 pipeline flow**: a horizontal 3–4 step process, with thick arrows between steps labeled with the action name above (e.g. "Data → Path design → Training → Sampling"), optionally with a loop-back arrow indicating iteration.
- **L6 sample grid**: an N×M array of result thumbnails (each cell the same size, 4 pt rounded corners), with small colored labels on the left or above marking conditions/step counts; for placeholder purposes only — real generated results must not be placed here.
- **L7 theorem + derivation, two rows**: a "Theorem" pill in the top row (pale blue background), a large formula card in the bottom row, with a peach figure on the right providing geometric intuition.
- **L8 problem list**: a pill-shaped small title (all-caps, muted gray) + 2–4 question-sentence body lines + a "design choice" sticky-note card at the lower right (pale blue background, pinned-corner shadow).
## 7. Chart / Table / Image / Component Rules
- **Charts**: line charts use 2–4 colors (primary blue, orange, green, gray), 2 pt line width with rounded end dots; axis labels use 10–11 pt gray text; omit tick marks and enclosing axis frames, retaining only pale-gray horizontal gridlines; the legend sits at the upper right or inside the chart. Bar charts use a single color or a two-color scheme, with 2 pt rounded bar corners and values optionally labeled on top. All axis labels must be present, using placeholder names.
- **Tables**: thin gray lines or no vertical lines, with alternating-row light backgrounds; the header may use colored background blocks (blue/magenta/teal each representing one method category); numeric values are centered, method-name columns are left-aligned; do not mix alignment styles within the same column.
- **Images**: always 4 pt rounded corners; a 9–10 pt italic gray caption below the image (source/conditions); multiple images are aligned to the grid with equal width and height; screenshots must not be placed directly on the page (they must be redrawn or replaced with self-produced placeholder images).
- **Rounded info cards**: 8–12 pt corner radius, 16×12 pt padding, a two-part structure of "small title (colored, 14 pt) + content"; a single-line pill bar uses a corner radius of half its height.
- **Bullet markers**: small dots (solid, primary color or gray), with only one nesting level allowed; points ≤ 4 lines, each line ≤ 12 words.
- **Warning/conclusion bars**: `Caveat` (magenta small title + gray-background card), `Open Problem` (magenta title + a centered question line), `Goal:` (teal pill + formula/short phrase).
- **Arrow annotations**: 1.5 pt line + solid triangular arrowhead; blue labels "process/average," magenta labels "limitation/dependency," with 12–14 pt text in the matching color.
## 8. Density and Spacing
- One central idea per page: 1 figure + ≤ 1 main formula + ≤ 4 lines of bullet points; exceeding this means splitting the page (prefer a build-up continuation page instead).
- Element spacing: title → content 24 pt; card → card 16–20 pt; figure → caption 8 pt; formula-card padding ≥ 16 pt; footer-line-to-content distance ≥ 20 pt.
- Within the same build-up series (same title across pages), every previously shown element stays pixel-for-pixel unmoved, with only incremental additions; new elements must fade in at a grid intersection point.
- White pages (transition pages with only a title + one sentence) are allowed, but at most 1 per section.
## 9. Footer and Page Numbers
- Footer: starting 12 pt above the bottom edge and 48 pt from the left, 9–10 pt italic gray text, containing a source/supplementary-note placeholder (replace with your own citation when reusing); multiple sources stack on new lines, and right-alignment is also acceptable.
- Page number: not displayed by default; if needed, 10 pt muted gray at the lower right, in the format `NN` (no prefix).
- Section pages and the cover/back cover carry no footer or page number.
## 10. Prohibited Items
- Do not copy any brand mark, institutional logo, conference name, or speaker name/avatar/photo from a source deck.
- Do not copy original sentences, original formula typesetting, original figures (contour plots, sample grids, loss curves, comparison-table data), or real experimental values; charts may retain only their type and color rules — data must be recreated as placeholder values.
- Do not reuse QR codes, external links, or citation entries as-is; link and citation slots should be presented as placeholder cards.
- Do not mix photographic/realistic-style illustrations into the diagram system; diagrams stay vector-flat + peach background.
- Do not use dark/pure-black background pages, gradient content pages, 3D-realistic charts, or overly heavy card shadows.
- Do not exceed 3 accent colors on a single page, nest bullet levels beyond 1 level, or use a serif font for content-page body text (serif is reserved for formulas only).
## 11. Delivery Checklist
- [ ] 16:9 canvas; 48 pt left/right and 40 pt top/bottom safe margins observed throughout.
- [ ] Ceremonial pages (cover/agenda/divider/back cover) use the four-stop pastel gradient; content pages use a near-white solid color, with the two skins never mixed.
- [ ] All 9 tiers of the font hierarchy table are present: H1, section number, H2, pill title, body, formula, inline coloring, footnote, table text.
- [ ] All colors come from the tokens; the blue/magenta/teal semantics are fixed (process/warning/condition); accent colors per page ≤ 3.
- [ ] All diagrams use a unified peach canvas block + orange-red contour-line language, with a consistent size series.
- [ ] Formulas use serif italics, with protagonist formulas occupying their own card; arrow annotations replace parenthetical notes.
- [ ] The eight layouts (L1–L8) can cover all pages; build-up continuation pages have zero displacement of existing elements.
- [ ] Charts/tables/images follow the rules in Section 7; no real data, screenshots, or photos of any kind.
- [ ] Footer uses 9–10 pt italic gray placeholder citations; page numbers follow Section 9; ceremonial pages have no footer or page number.
- [ ] The entire document contains no brand, no person's name/avatar, and no original text/figures/data; links/QR codes are placeholders.
- [ ] The file is UTF-8; this file's first non-empty line is a level-1 heading.
- No cards by default: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment: lines, whitespace, and font-size differences are the superior solution
- No evenly-divided composition: unless there is no other usable layout, do not default to three-way splits, four-way splits, or 2×2 matrices. This includes three-part conclusions such as three-column + title + conclusion

# Editorial Growth Courseware · PPT Design System (brand-free, reusable version)
This system is abstracted from a complete source deck of corporate brand and growth-methodology courseware, retaining only the layout, color relationships, and teaching narrative. It is not a reproduction of the source deck: it carries no platform mark, company name, person, photo, original text, case data, or product interface. All colors, dimensions, and values are approximate tokens; when generating, this file should serve as the constraint, with the user's query as the sole source of content.
Applicable scenarios: B2B brand courses, marketing-capability training, growth-methodology workshops, brand-and-demand-alignment explanations for management.
## Visual DNA
- **Editorial paper feel**: content is organized through generous whitespace, thin dividers, short paragraphs, and prominent section numbers; each page advances only one teaching conclusion.
- **Calm base color + a single warm accent**: the base color is near paper-white or extremely light gray, with structural text in deep-blue ink; warm yellow or coral is used only to mark emphasis, action, or results — never as full-screen decoration.
- **The section number is the navigation anchor**: section pages may use an oversized semi-transparent number or a narrow color bar to indicate progress; the number expresses only sequence and carries no statistic beyond what the query provides.
- **Method first, cases later**: principles are first broken down into actionable steps, then verified with anonymous, fictional scenario cards; cases must not become a brand showcase wall.
- **Lightweight illustration**: prefer geometric color blocks, wireframes, arrows, and abstract human silhouettes; do not use photos, real webpage screenshots, or icon stacks.
## Canvas and Grid
- The output aspect ratio is fixed at 16:9 (recommended 1280×720 or equivalent), even if the source deck was portrait-oriented — only its editorial pacing is borrowed, not its portrait ratio.
- Safe margins are about 6% left/right, about 7% at the top, with 7% reserved at the bottom as the footer band. The title, section number, and page number keep the same baseline throughout.
- Use an implicit 12-column grid: the title and main text occupy 7 columns, with evidence/cards on the right occupying 5 columns; a full-width data page may occupy 10 columns while retaining two columns of breathing room.
- Section pages may include a narrow color band extending from left to right; content pages remain paper-white, without a large color block pressing down on the text.
## Font Hierarchy
- Use Liter (English) and MiSans (Chinese); do not use brand-imitation letterforms. Numbers may use a semi-bold weight of the same font.
| Tier | Purpose | Approximate size (1280 width) | Weight | Color |
|---|---|---:|---|---|
| Cover title | One-sentence thesis | 42–50px | Bold | `--ink` |
| Page title | Conclusion sentence | 30–38px | Bold | `--ink` |
| Section number | Navigation mark | 54–90px | Regular/Bold | `--accent` at 20% opacity |
| Card title | Principle/action name | 20–24px | Bold | `--ink` |
| Body text | Explanation, steps, notes | 15–18px | Regular | `--body` |
| Footer | Source placeholder, page number | 10–12px | Regular | `--muted` |
Titles should preferably state a conclusion or a question, not an empty section label like "Contents" or "Introduction." Each body line should not exceed about 26 words; keywords are emphasized with weight rather than a second accent color.
## Color Tokens
- `--paper`: paper white `#FBFAF7`, the background of content pages.
- `--paper-cool`: cool light gray `#F1F3F5`, used for card backgrounds or section dividers.
- `--ink`: deep-blue ink `#102A43`, for titles, axis lines, and primary text.
- `--body`: dark blue-gray `#334E68`, for body text and explanations.
- `--muted`: blue-gray `#829AB1`, for footers, secondary tick marks, and borders.
- `--accent-yellow`: bright warm yellow `#F4C95D`, used for principle numbers, action markers, and a single point of emphasis.
- `--accent-coral`: soft coral `#E98B73`, used only for result/risk callouts — pick one or the other, never using it as decoration alongside warm yellow at the same time.
- `--line`: light blue-gray `#D9E2EC`, for dividers and table rules.
- `--dark-panel`: deep indigo `#243B53`, used only for a single dark closing page or code-style explanation.
Choose at most one primary accent color per page; warm yellow and coral may coexist only when their semantics are genuinely different (action vs. risk), and each must occupy less than 10% of the page.
## Page Skeleton
A six-page template progresses through "recognize the problem → form principles → turn into action → check the closed loop":
1. **Cover thesis**: paper-white background, a left-aligned conclusion sentence, an abstract geometric composition on the right; a small section number or short color band sets the tone.
2. **Why now**: one question sentence + three anonymous signal cards; the cards display only settings given by the query, without introducing source-deck data.
3. **Three principles**: three horizontal cards or a vertical staircase, each card with one verb, one explanation, and one observable behavior.
4. **Action combination**: a matrix/process connects audience, touchpoints, content, and cadence; an accent color points out the currently prioritized action.
5. **Verification and cases**: fictional before/after comparisons or a funnel on the left, with "what to look for/how to judge" on the right; all numbers must come from the query or be clearly marked as examples.
6. **Action closed loop**: a dark or light closing page giving the next step, a placeholder for the owner, a review cadence, and a reusable checklist; do not use a plain "thank you" page.
## Reusable Layouts
- **E1 conclusion + side card**: 60% conclusion and three pieces of evidence on the left, 40% a large number/abstract graphic on the right.
- **E2 three-principle cards**: three equal-width columns of cards, with the section number at the card's top and one line at the bottom stating "what counts as done."
- **E3 staircase path**: a four-tier horizontal staircase expressing progression from awareness to action, with connecting lines using only thin lines and arrows.
- **E4 2×2 choice matrix**: the horizontal/vertical axes each represent one judgment dimension explicitly given in the query, with only short labels placed within the quadrants — do not fabricate rankings.
- **E5 before/after comparison**: the same component in two rows, with the change explained on the left and direction shown with a same-colored bar on the right; using real case screenshots from a source deck is prohibited.
- **E6 closing checklist**: a deep-indigo or paper-white background, three "this week's actions" + one "next review," leaving ample whitespace at the bottom.
## Chart/Table/Image/Component Rules
- **Big-number card**: shows only one number and its unit, with the measurement basis/target written below; a number without a source uses an "example" label, without faking precision.
- **Funnel/path diagram**: at most four tiers, direction left to right; each tier uses only shades of a single color, no rainbow gradients.
- **Matrix**: axes, quadrants, and labels use `--ink`/`--line`, with the accent color marking only one recommended region; the judgment basis must be written beside it.
- **Process and loop**: use rounded rectangles + thin arrows, with step numbers matching the section number; a loop-back must label its trigger condition and review action.
- **Tables**: at most five columns, no vertical lines, with light lines between rows; headers are bolded, and key rows are marked with an accent-colored left border.
- **Images**: prefer abstract geometric placeholders, wireframes, and self-drawn graphics; do not place photos of people, brand logos, product interfaces, or source-deck charts.
- **Cards**: 8–12px rounded corners, 1px border, avoiding heavy shadows; leave at least 16px spacing between cards.
## Density and Spacing
- One repeatable conclusion per page, with body text not exceeding 6 items; on a three-card page, each card should not exceed about 35 words.
- Title to body 32–48px, between paragraphs 14–18px, card padding 18–24px; effective content area about 55–70%.
- The cover and closing pages are low density; the method-matrix and case pages are medium density; do not solve excess content by shrinking the font — cut content or split the page instead.
## Footer and Page Numbers
- Content pages place a page number in the form `01/06` at the lower right, 10–12px `--muted`; section pages may show only the section number.
- The lower left may carry an "internal working draft/example" placeholder, but must not carry a source brand name or a copied copyright mark.
- The cover and closing pages may omit the footer; if retained, use the same gray value and the same baseline.
## Prohibited Items
- Do not copy any platform/company logo, trademark, person, case name, original sentence, real data, or product screenshot.
- Do not use large areas of brand blue, gradient text, glow, heavy shadows, skeuomorphic icons, or decorative photos to manufacture a "marketing feel."
- Do not use empty words like "brand," "growth," or "exposure" as titles; a title must be able to guide a judgment or an action.
- Do not use a percentage without a stated unit and measurement basis, and do not write an anonymous example as if it were a real client result.
- Do not use multiple highly saturated accent colors on the same page, and do not let a wall of cards replace narrative.
## Delivery Checklist
- [ ] The aspect ratio is 16:9, with the title/section-number/page-number baseline consistent.
- [ ] Each of the six pages has one conclusion, with no table-of-contents page, plain thank-you page, or blank transition page.
- [ ] At least one principle-card page, one action-matrix page, one before/after comparison page, and one action-closed-loop page are present.
- [ ] Each page uses only one primary accent color, and color carries a clear semantic meaning.
- [ ] All numbers come from the query or are marked as examples, with the unit and measurement basis stated.
- [ ] No source-deck brand mark, person, photo, screenshot, original text, original data, or identifiable case is present.
- [ ] Cards, tables, processes, and charts are all readable at projection distance, with whitespace ratios not compressed.
- No cards by default: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment: lines, whitespace, and font-size differences are the superior solution
- No evenly-divided composition: unless there is no other usable layout, do not default to three-way splits, four-way splits, or 2×2 matrices. This includes three-part conclusions such as three-column + title + conclusion

# Blue-Line Experiment Methodology Courseware · PPT Design System (brand-free, reusable version)
This system is reverse-engineered from a complete experiment-and-measurement-methodology courseware, abstracting only the teaching pacing, method matrices, comparison expression, and editorial layout. Do not copy the platform name, company, person, case, photo, screenshot, original text, or real metric from the source deck; the facts and numbers in the generated deck may come only from the user's query.
Applicable scenarios: marketing-experiment training, product-trial design, growth-team workshops, management-level experiment-governance explanations.
## Visual DNA
- **Handout-style section structure**: each chapter is cut apart by a prominent number, a short title, and a color band; the body reads like a printable operations manual — defining first, then demonstrating.
- **A blue line runs throughout**: deep-blue thin lines, arrows, and axes string the pages into one path of "form a hypothesis — split groups — measure — act"; the line matters more than any icon.
- **Highlighting only signals**: yellow/orange is used for hypotheses, caveats, or next steps, in a small, fixed-position area; the rest of the information is layered in black, gray, and light blue.
- **Comparison first**: control vs. treatment group, before vs. after, input vs. result are all displayed side by side using the same geometric component, without flashy 3D graphics.
- **Cases are practice material**: case pages only demonstrate how the method lands in practice, using anonymous fictional scenarios instead; they do not reproduce a source deck's client narrative or results.
## Canvas and Grid
- Output is uniformly 16:9 (1280×720 or equivalent); the source deck's portrait reading pace is translated into horizontal columns rather than copying its original page ratio.
- Margins are about 5.5% left/right, 7% at the top, 8% at the bottom; the section number and page number are fixed at the upper-left and lower-right anchor points.
- Use a 12-column grid: definition text occupies 5 columns, the method diagram occupies 7 columns; comparison pages use a 5:5 two-column split, with 2 columns left in the middle for connecting lines.
- Lines use 1–2px width, with connecting lines always directional; large color blocks appear only on section pages or a single dark summary page.
## Font Hierarchy
- Use Liter for English and MiSans for Chinese; process labels and numbers may use the same font's semi-bold weight, with JetBrains Mono (brought in via customFonts) reserved for code or formulas.
| Tier | Purpose | Approximate size (1280 width) | Weight | Color |
|---|---|---:|---|---|
| Cover title | Method thesis | 40–48px | Bold | `--ink` |
| Page title | Conclusion/question | 30–36px | Bold | `--ink` |
| Section number | Progress navigation | 48–76px | Bold | `--accent-blue` |
| Method label | Hypothesis, control, treatment, etc. | 16–20px | SemiBold | `--ink` |
| Body text | Definitions, steps, explanations | 15–18px | Regular | `--body` |
| Annotation/footnote | Measurement basis, limitations, page number | 10–12px | Regular | `--muted` |
Write titles as "the judgment this page must produce," not empty section names like "Methodology" or "Best Practices." Every chart must be accompanied by one sentence of "how to read it/what it means."
## Color Tokens
- `--paper`: warm white `#FCFCFA`.
- `--ink`: deep indigo-blue `#14213D`, for titles, the main line, and axis lines.
- `--body`: blue-gray `#3E536B`, for body text.
- `--muted`: gray-blue `#8C9AA8`, for footnotes and auxiliary lines.
- `--line`: light blue-gray `#D8E2EA`, for dividers and grids.
- `--accent-blue`: medium-bright blue `#2F80ED`, for section numbers, the treatment group, or the main path.
- `--accent-yellow`: warm yellow `#F2C94C`, for hypothesis/key-point callouts; choose only one spot as the primary emphasis.
- `--accent-orange`: orange `#F2994A`, for risk/to-be-verified callouts; must not be used as decoration simultaneously with yellow.
- `--control`: gray-blue `#9FB3C8`, for the control group or baseline.
- `--deep-panel`: deep blue `#203A5F`, for the summary page or method box, not for an ordinary content-page background.
By default, each page enables only `--accent-blue` plus one semantic accent color (yellow or orange). The control and treatment groups must both be labeled with text in the legend — do not distinguish them by color alone.
## Page Skeleton
A six-page template progresses through "problem — method — verification — scaling":
1. **Cover**: one experimental thesis sentence, a section number, and a blue line; geometric nodes hint at the path, with no photo or brand mark.
2. **Why experiment**: a question sentence + three common misconceptions, with the boundary of the judgment to be verified this time given at the bottom.
3. **Hypothesis and grouping**: the hypothesis structure on the left, with control/treatment columns on the right explaining the input, what stays constant, and the observed metric.
4. **Method selection**: use a two-dimensional matrix or decision tree to select the test type, clearly stating when it does not apply; all labels use the user query's own terminology.
5. **Read results and act**: an anonymous example's before/after comparison, a confidence-interval placeholder, or a result card, immediately followed by the criteria for "continue / adjust / stop."
6. **Scaling closed loop**: an owner, a timeline, a review cadence, and an experiment log form the loop; the final sentence is an executable next step, not a thank-you page.
## Reusable Layouts
- **M1 hypothesis card**: an `If … then … because …` three-line structure, with the falsifiability condition written at the bottom.
- **M2 two-group comparison**: control group / treatment group side by side, with what stays constant written at the top and the single changed variable written at the bottom.
- **M3 decision tree**: at most three branch levels; each leaf node states "applicable/not applicable" rather than an abstract noun.
- **M4 method matrix**: the horizontal axis is the observation period or intervention intensity, the vertical axis is a user-given dimension such as randomization or geographic scope; the recommended cell gets a yellow border.
- **M5 result card**: four lines — metric, direction, interval/measurement basis, action; if there is no interval, explicitly write "evidence pending."
- **M6 closed-loop swimlane**: four segments — propose → execute → analyze → review — with a role placeholder marked beside each lane, avoiding fabricated names.
## Chart/Table/Image/Component Rules
- **Comparison bar**: the control group in gray-blue, the treatment group in blue; both bars start from the same zero point, directly labeling the direction and unit of the difference.
- **Timeline**: a single blue line connects the baseline, intervention, observation window, and decision point; each node states only one action.
- **Interval chart**: prefer point estimates + error bars or an interval band; do not truncate axes, hide sample size, or present correlation as causation.
- **Decision matrix**: the axis titles, applicability boundary, and "do not use" region must all be present; avoid treating a four-quadrant layout as decoration.
- **Tables**: at most five columns, six visible rows; the first column is the question/hypothesis, the last column is the action or evidence status.
- **Images**: use only self-drawn abstract graphics, wireframe devices, and geometric placeholders; photos of people, product interfaces, logos, and original source-deck charts are prohibited.
- **Formulas/code**: use a monospace font in a light-colored code box, at most 8 lines; explain the input, output, and limitations beside it.
## Density and Spacing
- One judgment per page; body text does not exceed 6 items, decision-tree nodes do not exceed 8, and each matrix axis does not exceed 4 labels.
- Title to main figure 28–44px, spacing between components 16–24px, at least 8px of gap between lines and text; effective content area about 60%.
- Definition pages are low density, method-matrix pages are medium density, result pages are medium-low density; do not shrink the font to cram in more experiment types.
## Footer and Page Numbers
- The lower right uses a `01/06`-style page number, the lower left carries small "measurement basis/hypothesis/example" text; both use `--muted`.
- When a source is needed, write only an anonymous "internal setting/public methodology reference," not a source-deck brand name or a copied copyright line.
- The cover may omit the footer; the closed-loop page retains the page number for reference during reviews.
## Prohibited Items
- Do not copy any platform, company, client, person, trademark, photo, interface, original text, real result, or number from the source deck.
- Do not describe an observational correlation as causal, and do not omit the control group, sample definition and sampling basis, time window, or limitations.
- Do not use rainbow colors, glowing particles, heavy shadows, 3D perspective, or complex illustrations in place of a clear experimental relationship.
- Do not use baseline-free promotional language such as "significantly improved" or "comprehensively leading"; without evidence, write "to be verified."
- Do not let a matrix, process, or big-number card exist independently, detached from the page's title conclusion.
## Delivery Checklist
- [ ] The aspect ratio is 16:9, with the section number, title, and page number sharing a consistent baseline.
- [ ] The six pages cover, in order, the problem, hypothesis grouping, method selection, reading results, and the scaling closed loop, with no table-of-contents or thank-you page.
- [ ] At least one control/treatment comparison page, one method-matrix or decision-tree page, and one result-criteria page are present.
- [ ] Charts clearly state the unit, measurement basis, time window, and limitations; if missing, mark them as evidence pending.
- [ ] Each page enables only one semantic accent color, with both the control and treatment groups carrying text labels.
- [ ] All numbers come from the query or are marked as examples; there is no brand mark, person, photo, screenshot, original text, or source-deck data.
- [ ] The generated PPTD/PPTX opens correctly, the per-page screenshot count matches the page count, and text is readable at projection distance.
- No cards by default: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment: lines, whitespace, and font-size differences are the superior solution
- No evenly-divided composition: unless there is no other usable layout, do not default to three-way splits, four-way splits, or 2×2 matrices. This includes three-part conclusions such as three-column + title + conclusion

# Organization Name — Q2 2025 Crypto Industry Report STYLE DESIGN SYSTEM
## 1. Style Positioning
A dark, data-driven PPT design system for quarterly crypto-industry research reports, aimed at professional readers fluent in metrics across markets, assets, trading volume, ETFs, DeFi, NFTs, and exchanges, supporting high-density data, longer explanatory text, and multi-series charts. The body adopts a dark research dashboard with Organization Name's green visual identity; the cover, section dividers, and product/closing pages use high-saturation green or purple frames, large rounded cards, and mascot illustrations.
The whole deck is a 16:9 landscape canvas; content pages use a near-black background with white ultra-heavy sans-serif titles (Archivo Black, via customFonts), body and footnotes in Inter (via customFonts); the header holds a fixed small brand wordmark; the footer contains the report name, copyright, sources, and page numbers. Main content includes line, column, stacked-column, and area charts, timelines, tables, and text lists/avatar matrices; accent colors are fluorescent green, purple, pink, yellow, and other high-saturation colors.
Underlying principles:
1. **Data over decoration.** Pages prioritize charts, tables, numbers, and explanatory text; illustrations, borders, bright colors, and identity marks are used only for brand recognition, classification, emphasis, or section transitions.
2. **Body-skeleton consistency over layout showboating.** Ordinary data pages keep the black background, upper-left brand mark, white title, insight line on the right or above, and bottom sources and page numbers; large-area green/purple brand pages appear only at the cover, section dividers, product, or closing positions.
3. **Accent colors must carry semantics.** Fluorescent green is used for the brand, positive/growth values, key series, or button-like components; purple/pink for insight lines, section transitions, and special annotations; red only for negative change or risk-type data. If bright colors hinder reading values, prioritize the clarity of axes, labels, units, and legends.
## 2. Page Skeleton
The canvas is 16:9 landscape widescreen. Content-page backgrounds are pure black or near-black; covers/section/closing pages use a bright-green outer background, or a purple outer frame with a dark rounded inner card. Keep stable margins with no key data at the outer edges; high-density pages may approach full-bleed, but the header, title, and footer must keep their safety zones.
**Cover page**: bright-green outer background with a large deep-green rounded card at the center, and a notch-style split or dual-card structure at the top. The upper left holds the identity mark — plain small text with the new topic name, or left blank; no graphic logo is drawn. The main title is huge, the year or keywords may be layered with a dark-green/light-green gradient feel, and the report name is in white/light green; the lower middle holds the Organization Name mascot illustration, a thin-line trend line, and halftone dots; the sponsor text list sits at the right or lower right, smaller in area than the main title and the mascot.
**Table of contents page**: black background with a large "Content"-style title at the upper left; the body is a multi-column contents list, with level-one section titles larger and white, entries in small white/gray text, and page numbers right-aligned; author avatars, names, and titles may sit below. The contents page uses no large charts and little decoration.
**Section dividers**: a bright-green or purple outer frame/background, with a large deep-green or deep-blue-black rounded card inside. The left holds the section name and a small label; the right or bottom holds the large Organization Name mascot and theme graphics. Section titles take the dominant level, with minimal information.
**Content data pages**: a fixed small brand wordmark at the upper left, with the white page title below it or to its right; the title area occupies a compact horizontal band at the top. The insight line sits to the right of the title, at the page's upper right, or atop the explanation column, usually opening in purple and continuing in gray-white text. The body may use a single large chart, left-right columns, chart + explanation column, a timeline, a table, or a matrix. The bottom left holds the report name/copyright, Source sits below the chart or at the lower left, and the page number sits at the lower right. Reading path: brand and title → purple insight line/key information line → main chart or table → explanatory text/legend → source and page number.
Dividers are used only for chart axes, table lines, card borders, and timeline rules — no heavy header rules are set. Content pages use no watermarks or large background graphics; backgrounds stay clean.
## 3. Content Organization
Titles are object-type or metric-type, such as "a certain asset's price and trading volume," "a certain market share," "notable events," or "exchange trading volume," responsible for topic positioning; conclusions are expressed by the insight line. Titles should be 1 line, 2 lines if necessary; avoid more than two lines, which compresses the chart area.
Each page prioritizes one information line, located to the right of the title or atop the explanation column, structured as "key change/conclusion + data definitions and measurement basis/time range + cause or impact." Use purple to highlight the opening phrase or core number, with the rest in gray-white. Do not stack multiple conclusions into one paragraph; each page prioritizes one main judgment.
The body uses short paragraphs and bullets, usually in the narrow column to the left or right of a chart; each paragraph explains one cause, data finding, or impact. Keep paragraphs broken and line lengths moderate; the text column in left-right layouts exists to explain the chart and does not become a long article on its own.
Group by market category, asset class, time, platform, chain, exchange, or metric definition and basis. High-density pages use subtitles, labels, legends, colored series, and thin-line separation. A single page carries one core question; it may contain multiple data series, but must not discuss multiple unrelated topics at once.
Numbers and units stay close to data labels or axes, retaining the relevant formats and units — percentages, dollars, multiples, dates, and quarters. Time axes remain continuous and readable; big numbers may be highlighted in the insight line or chart annotations. Source footnotes sit below charts or in the footer, in small gray-white text that does not compete with the main data.
## 4. Content Page Layout System
**A. Left explanation column + right large chart**
Suited to single-theme time series such as price, trading volume, index, and capital flows. The left column holds the title, insight line, 2–4 explanation paragraphs, and the source; the right large chart occupies most of the body width, complete with axes, legend, and data annotations. Emphasize with bright lines, peak labels, vertical annotation lines, or key-point text. Not suited to table-type content requiring extensive categorical comparison.
**B. Top title-and-insight + full-width chart below**
Suited to horizontal time-axis charts such as multi-series lines, stacked columns, and market-share change. A compact title and one insight line sit on top; the main chart spans the page; the legend stays near the chart's top or right, and series colors keep high contrast. If there is too much explanation, switch to left-right columns to avoid compressing chart height.
**C. Large chart + right annotation/sponsor/note column**
Suited to pages needing supplementary event background, such as IPOs, ETFs, and trading volume. The main chart sits on the left or in the middle; the right narrow column holds short notes, wordmarks, or secondary legends; the right column must not exceed the main chart in width. This layout is not suited to multiple long paragraphs or multiple unrelated wordmarks.
**D. Timeline/event-band layout**
Suited to "Notable Events"-type content. Use multiple rows of horizontal date bars; date blocks distinguish periods or categories with high-saturation green, pink, purple, etc., with small-size event notes beneath; the title area is minimal. Do not add complex charts; event copy must be short — long explanations break the timeline rhythm.
**E. Table/ranking/matrix page**
Suited to asset returns, stablecoins, exchanges, chain ecosystems, and team or platform comparisons. The body uses dark tables, ranking bars, text lists, or multi-column cards; a note column may sit on the left, and colored bars, dots, icons, or text color highlight positive/negative change inside the table. This layout suits high-density classification, not continuous trends.
**F. Brand/product/section-style body variant**
Uses green or purple cards, buttons, screenshot-style interfaces, and the mascot for product promotion, section intros, or closing pages; lower information content than data pages. Must not be abused as a template for ordinary research pages.
## 5. Color System
**Background black / near-black #000000–#080808**: the main background of content pages, largest in area. Cannot be replaced with light colors; even if the new theme uses a brand color, keep body backgrounds dark.
**Deep-green cards #183F2D / #1A412E**: the main base color of covers, section dividers, and brand cards, usually paired with bright-green outer frames. Brand pages may use it over large areas; ordinary content pages use only small amounts for labels or borders — it should not replace the black background over large areas.
**Fluorescent green #A6F05F / #9EE45A / #4BCC00**: used for the cover outer base, section frames, identity marks, positive values, key data lines, button-like labels, and a few chart series. Area may be large on brand pages and small-to-medium on content pages. It may be replaced with a new brand primary color, but must keep dark-background high contrast and consistent "positive/key" semantics.
**White #FFFFFF / light gray-white #DDE5E0**: used for titles, key labels, main axis text, and high-priority numbers. Cannot be replaced by low-contrast colors.
**Gray-blue/gray-green text #8A9492 / #B9BCA6 / #808963**: used for body text, notes, secondary legend text, axis labels, sources, and footers; low brightness, but never so low as to be unreadable.
**Purple #7A54FF / #6B4CFF**: used for section dividers, insight-line openings, key lines, labels, and brand variants, at small-to-medium areas; it does not represent positive/negative status by default.
**Pink #F19EE2 / #F4A0E5**: used for event timelines, chart series, and emphasis blocks, at small areas, expressing categories. Avoid large simultaneous use with purple, which becomes garish.
**Yellow #FAEB6A / #E7D84A**: used for column charts, key values, event or return-type series; not for long text passages.
**Red/coral #FF5A6A / #BE827F**: used for negative returns, declines, risks, or negative values. For status/data only, never as decoration.
Content pages keep their main hues to black-white-gray + 1 brand accent + 2–4 data series colors. Multi-series charts may add colors, but legends must stay clear; color serves classification/status only — no meaningless decoration.
## 6. Fonts and Text Hierarchy
Fonts are modern sans-serif: titles use Archivo Black (via customFonts); body is dominated by Inter (via customFonts), with weights handled through the bold field. Chart axis/category labels may use a serif italic (e.g. EB Garamond Italic via customFonts); everywhere else, do not mix in serif or handwritten fonts; special sponsor/logo fonts exist only as images or marks.
With body note text = 1x:
- **Cover main title/year**: approx. 4–6x, bold or semi-bold, tight letter spacing allowed.
- **Section titles**: approx. 3–5x, white or light green, usually 1–2 lines.
- **Content-page titles**: approx. 2–3x, white, medium-bold to bold.
- **Insight line/information line**: approx. 1.4–2x, usually medium-bold, purple keywords + gray-white continuation.
- **Subtitles/group titles**: approx. 1.1–1.4x, medium-bold or semi-bold, white/light gray.
- **Body paragraphs and bullets**: 1x, regular weight, gray-white or gray-blue.
- **Table text/chart labels**: approx. 0.7–1x, compress per space, keeping numbers readable.
- **Footnotes, sources, footers, page numbers**: approx. 0.6–0.8x, gray, low-level but never absent.
Numeric labels use the same fonts as body text, with increased weight or a different color; no ornamental numeral forms. Titles and body build hierarchy through size, weight, and color, without relying on shadows or strokes.
## 7. Chart Language
Core charts include line charts, column charts, stacked columns, area charts, dual-axis price/volume charts, horizontal-bar rankings, timelines, share/market-share charts, donut/pie mini-widgets, and tabular leaderboards.
Charts use dark bases; axes and gridlines are low-brightness gray thin lines; no white-background chart boxes. Main data lines use high-contrast colors such as fluorescent green, yellow, purple, pink, and cyan; secondary series lower saturation or line width. Column charts use bright columns against the dark grid, and volume columns may combine with price lines. Multi-series stacked columns need clear legends, placed above the chart, to the right, or in empty chart areas.
Key data uses peak/trough labels, vertical event lines, endpoint values, local text annotations, color brightening, and red for negative values. Annotations stay close to their points and should not form long passages. Forecasts, targets, or baselines use dashed/thin lines and explicit labels, distinguished from historical data; never let a forecast line blur into an actual line.
Axes keep units and time bases — especially dollars, percentages, quarters, dates, and trading volume. Gridlines must be thin, dark, and few; no heavy borders. The page title states the chart's subject; the chart itself keeps only the necessary subtitle and legend, avoiding repetition.
## 8. Tables and High-Density Information
Tables are used for rankings, asset comparisons, exchange/chain/protocol metrics, returns, market share, and team/author information. They adopt a dark-base, high-density style: headers in white or light-gray medium-bold text, row-column dividers in low-brightness thin gray, and cells usually without obvious fills; when necessary, use dark gray/deep green for light zoning.
Number columns are right-aligned or visually aligned by decimal point; text columns left-aligned; name columns may add small icons or circular token placeholder blocks. Positive/negative values are distinguished in green/red; rankings or strength may use horizontal bars, color-block lengths, heat colors, or small dots. Summary rows or key rows use brighter text, thin borders, or a light fill — but no heavy highlight fills.
High-density side-by-side modules use cards, column groups, text lists, or small chart collections. Each module keeps a title, a key value, and one minimal explanation; modules are separated by alignment, spacing, and thin lines — no large shadows. Zebra striping is not a primary language; extremely low-contrast dark gray may be used cautiously, and where dividers suffice, no zebra striping is added.
If a table exceeds what one screen can scan, split it into multiple pages or focus on the Top N — do not compress it into illegibility.
## 9. Components and Graphic Elements
**Brand wordmark header**: fixed at the upper left of content pages, small in size, white brand word + green "Research." Keep it on new pages; do not enlarge it into decoration.
**Insight line component**: purple keyword/opening + gray-white explanation, located to the right of the title or atop the body column; at most one main insight per page — avoid multiple purple sentences competing.
**Rounded brand cards**: covers, section pages, and product pages use large rounded deep-green/deep-blue cards with bright-green or purple outer frames. Content data pages do not by default frame all content in large cards.
**Labels/badges**: used for section codes, asset symbols, button-like CTAs, or chart categories; outlined rounded rectangles or bright fills with short text. Cannot carry long sentences.
**Thin dividers and axis lines**: low-brightness gray lines for tables, charts, and timelines; thin and restrained — no decorative thick lines.
**Event timeline blocks**: horizontal date color blocks + event notes beneath, colored by date period or category. Suited to event lists, not numeric trends.
**Text lists/avatar matrices**: used for contents-page authors, sponsors, exchanges, ecosystem projects, etc.; institution names are presented as text lists or neutral placeholder blocks, avatars may remain; unified sizes, alignment, and label text. Do not mix in colorful icon decoration; no graphic logos are drawn.
**Mascot illustrations**: the Organization Name green/purple character is used on covers, section dividers, and closing pages. On ordinary data pages it may appear only on special brand/product pages, and must not cover charts.
## 10. Texture and Prohibited Items
Overall flat, dark, data-driven, and restrainedly branded; content pages rely on color contrast, type-size hierarchy, chart density, and alignment — not photography, complex textures, shadows, or 3D.
**Prohibited**: on ordinary content pages, large-area photo backgrounds, complex gradient backgrounds, 3D graphics, glowing strokes, emoji, garish illustrations, decorative colorful icons, large stretches of centered copy, heavy shadows, low-contrast gray text, unsourced charts, unit-less numbers, or decorations covering axes.
**Use with caution**: rounded cards, large-area bright-green bases, large purple blocks, text lists, avatars, screenshot-style interfaces, donut mini-charts, zebra-striped tables. They must serve an information function or a brand-node function — never added just to fill whitespace.
**Special pages allowed**: covers, section dividers, product pages, and closing pages may use the mascot, large rounded cards, bright-green/purple outer frames, halftone dots, trend-line backgrounds, and sponsor text lists. Even on special pages, keep the title readable and never let brand elements overshadow the main information.
Images/screenshots are not the core language of the body; if they must be used, place them within fixed boundaries with a title and a source — no fullscreen photographic storytelling. If gradients appear, they are limited to subtle treatment of the cover title or brand atmosphere, not a body-background system.
## 11. Generation Checklist
- Skeleton: is it 16:9; are content pages black-based; is there a small brand wordmark at the upper left; does the footer include the report name/copyright, sources, and page numbers?
- Copy: is the title a clear object/metric; is there only one main insight per page; is the body in short paragraphs or bullets; do numbers carry units, time ranges, and measurement bases?
- Hierarchy: are the title, insight line, body, chart labels, and footnotes separated by relative sizes and colors; is dependence on specific font sizes avoided?
- Color: does it stay at black-white-gray + fluorescent green/purple + necessary data colors; are positive/negative states clearly green/red; are there too many bright colors on one page?
- Layout: does the main chart/table occupy the largest area; does the explanation column assist the chart; is there meaningless whitespace or overcrowding?
- Charts: are axes, units, legends, gridlines, data labels, and emphasis annotations complete; are multi-series colors distinguishable; are forecasts/baselines marked?
- Tables: are headers, alignment, dividers, key rows/columns, and positive/negative colors consistent; is text readable; is over-compression avoided?
- Components: do rounded cards, labels, timelines, wordmarks, and the mascot appear only on appropriate pages; do they serve information rather than decoration?
- Prohibited items: no photo backgrounds, emoji, 3D, glow, heavy shadows, complex textures, meaningless icons, or large stretches of centered copy.
- Quality: check overflow, truncation, garbled text, overlap, low contrast, occlusion, empty content, wrong chart proportions, missing page numbers, missing sources, and mechanical template repetition.
- No default use of cards: unless the user explicitly requests it, it is strictly forbidden to use rounded rectangles or rectangular cards to build hierarchy or alignment — line segments, whitespace, and font and font-size differences are better solutions.
- No equal-division composition: unless no other layout is available, do not default to three-way splits, four-way splits, or 2×2 matrices — including three-part structures such as three-way split + title + conclusion.
