/* A-Team site — direction A "signal grid".
   PALETTE: Face's kit (agents/.../brand-kit.md, 2026-10-27), applied as v2. Colour is a
   STATUS, not decoration: ink for the claim, saturation only where a claim is graded.
   Red can only ever mean a failed test, which is why links are ink + 2px underline and
   never a coloured accent. Re-run the contrast snippet in README.md after any change.
   No webfonts (system stack only), so there is no network request and no FOUT. */
