   LIQUID GLASS — FINAL PASS  (load this file LAST)
   ──────────────────────────────────────────────────────────────────────
   What this file does
   1. One shared glass recipe (tokens below) instead of 10 competing ones.
      Blur 12–24px / saturate ≤190%  →  crisp, true-to-palette glass.
      (The old 40–72px blur + 260–380% saturate over-boosted colours,
       which tinted anything behind the glass and cost heavy GPU time.)
   2. Layered edge light: top specular, warm bottom bounce, side rims,
      plus a soft light that FOLLOWS THE POINTER (set by js/premium.js).
   3. One easing language for every motion (expo-out + soft spring).
   4. Reveal animation that no longer freezes hover / tilt afterwards.
   5. Reduced-motion, no-backdrop-filter and mobile fallbacks.
