   CANARY — documentation design system

   Direction: scientific-report restraint. A serif display face against a
   neutral UI sans, hairline rules instead of shadows, and a single accent.
   Crimson is reserved for one thing only — the zero. Everything is driven by
   tokens, so light and dark are the same page with a different palette.
