/* FCHN Watch — glass design system.
   Minimal, high-tech, translucent. Surfaces are frosted panes floating over an
   ambient field; borders are hairlines; colour is reserved for state and is never
   decorative. Every class name from the previous system is preserved, so no markup
   had to change.

   THEMING: :root carries dark, :root[data-theme="light"] overrides. Nothing below
   the token blocks hardcodes a light- or dark-specific colour — if you find
   yourself typing rgba(255,255,255,…) or rgba(0,0,0,…) in a rule, add a token
   instead, or that rule will break in one of the two themes. theme.js stamps the
   attribute before first paint. */
