/* Shared tokens, reset and chrome.

   Visual language borrows from Wise: a warm off-white page with SOLID white
   cards sitting on it, very bold headlines on tight leading, full pills, and a
   bright lime used only as a fill with deep green type on top.

   That is a deliberate shift away from glass-on-white for the light theme —
   translucency needs something behind it to refract, and against a pale page it
   just reads as muddy. Depth here comes from the card being lighter than the
   page plus a soft shadow, which is crisper. The dark theme keeps real glass,
   because against a deep forest ground translucency actually reads.

   Accent vars (--accent fill, --accent-ink on-fill, --accent-text as type) are
   injected by js/brand.js from config.js. Never hardcode them here. */
