/* OpenMed Agent — color tokens ("clinical grade" design system).
   Light is the default scope; dark activates under [data-theme="dark"].

   ACCENT ENGINE: every accent-tinted value derives from --om-accent-base via
   oklch relative color (Chrome 119+ / Safari 16.4+ / Firefox 128+). Change ONE
   hex to retint an entire site (used for per-site accents across OpenMed
   properties). Chroma is clamped so any base stays calm and clinical;
   lightness is fixed per role for guaranteed contrast.

   FALLBACKS: custom properties cannot use the two-declaration fallback trick
   (an unsupported value poisons the var at computed-value time instead of
   falling back), so the engine lives in an @supports block below. The static
   values here were computed for #FF823A — if a sibling site changes
   --om-accent-base it must recompute these ten hexes for old browsers, or
   accept default-orange fallbacks there. */
