Visual parity pass against attack.mitre.org/# per user feedback ("trop dense,
illisible, je veux la même représentation"):
- Layout switched from flex+fixed-width 224px columns to a CSS grid of
`repeat(N, minmax(0, 1fr))` so the 15 tactic columns share the container
width equally. No more horizontal scroll on a standard desktop.
- Cells now show NAME ONLY (matches mitre.org). The external_id (TA00xx /
T1xxx / T1xxx.xxx) is preserved in the chip selection bar at the top and
in the `title` hover tooltip on every cell — surfaces on demand, doesn't
consume cell real estate.
- Font: switched to `font-sans` (IBM Plex Sans) at `text-xs` (12px) across
cells, matching the mitre.org typography. Headers use the same family at
the same size with a 10px sub-line for the technique count.
- Chevron icons: ▸ (collapsed) / ▾ (expanded) — small, sub-technique count
rendered inline beside the chevron.
- Helper line below the matrix tells the user where the IDs went.
Spec §F2 + testing-m4.md walkthrough rewritten to lock the new sizing rules
in (font-xs, no external_id in cells, hover/chip for the ID, no horizontal
scroll). spec-reviewer will see the matching contract.
DoD: make e2e → 34 passed. Selectors (data-testid + aria-pressed) unchanged
so the existing M4 e2e test still walks the new layout end-to-end.
