/* ===== LIQUID GLASS =====
   .glass         panel material (milky, blurred, rim-lit, pointer specular). radius: --radius-glass.
   .glass--strong brighter, for nav bar / primary surfaces.
   .glass-inset   a card sitting inside a glass panel (no blur stacking, just a lighter fill + rim).
   Rules: never put ::before/::after on a .glass element (they are the rim + specular).
          Don't nest .glass inside .glass (blur-on-blur goes muddy); use .glass-inset inside.
   glass.js sets --mx/--my on hovered glass and, in Chromium, replaces the blur with a per-pane lens filter (inline backdrop-filter). */
