/* ==================================================================
   REX — CORE design system
   ------------------------------------------------------------------
   Black glass, crimson light, hairline HUD geometry. One accent (red),
   one signal (mint, for "ok" states only). Every surface is solid or
   translucent paint — no backdrop blur — because the 3D core is
   animating behind it and a blur would be re-run every frame.

   The legacy tokens at the bottom of :root (--paper, --ink, --blue …)
   keep forms.css, account.js and downloads.js rendering correctly
   without touching them.
