/* Reef — design system
   One shared sheet for every page (landing, app, transparency, passport).
   Sans (Switzer) carries the whole UI; mono (Geist Mono) is reserved for
   addresses, hashes and tabular numerals only. One accent, used sparingly.
   Depth comes from 1px hairlines and low-alpha tints — never glow or glass.

   Token names the dashboard already references (--teal/--blue/--gold/--red/
   --success…) are preserved so app.html re-skins by VALUE; the marketing
   component layer is namespaced `.r-*`. */
