/* ============================================================
   THEME — Cupertino (light)
   -----------------------------------------------------------
   Standalone file for `[data-theme="cupertino-light"]` consumers.
   This is the ONE FILE users swap to reskin their site.
   Replace this file with any other theme.css to change the
   entire look & feel. Tokens only — no component CSS lives here.

   TOKEN CONTRACT
   -----------------------------------------------------------
   Every theme MUST declare every variable in this file, even
   if it sets it to a neutral value (e.g. --glow-md: 0 0 0 transparent;).
   That's what guarantees a clean one-file swap.
