# Fallback without LaTeX

Use this path only when `scripts/preflight.sh` exits 2. A fallback is not equivalent to the
TikZ package: say explicitly that cursor placement, ledger locking, face-data validation,
caption lanes and package warnings are unavailable.

## Preserve manually

1. Recompute the shape/semantics ledger before drawing.
2. Use one scale function from symbolic axis names to physical lengths; never size two
   occurrences of the same axis independently.
3. Keep scores, indices and masks in distinct grammars; preserve exact zeros and support.
4. Derive every placement from previous bounding boxes and one gutter constant.
5. Export SVG plus PNG and inspect both full-size and at 360 px using `checklist.md`.

Prefer SVG for editability. Use matplotlib only when it can emit SVG and the tensor cells
remain individually inspectable. Do not imitate package compliance in the delivery: name
the fallback renderer and list any inferred shape, convention or reduced guarantee.
