   showcase.css — page chrome for the showcase document.

   Layout geometry only. Every colour, type size, radius, shadow and duration is
   a token, so this page re-themes with the rest of the system instead of
   drifting away from it. Where a translucent or blended surface is needed,
   color-mix() blends tokens rather than introducing a literal colour.
