  /* ─── Categorical palette ────────────────────────────────────────────────
     Semantic tokens above answer "is this good or bad?". These answer "which
     one is this?" — workshop vs workshop, shop vs shop, integration vs
     integration — where the hue carries identity, not sentiment. Never reuse
     --success/--danger for that: a green workshop chip reads as "healthy".

     Each theme hand-tunes all 8 slots so the palette matches its own tone.
     tests/categorical-palette.test.ts asserts every slot holds >=4.5:1 under
     all three recipes below and stays >=0.088 apart in OKLab from its sibling
     slots. Retuning a hue by eye breaks one of those silently — change a value
     and run `pnpm test tests/categorical-palette.test.ts`. */
