   Cardinal glass theme.
   Loaded AFTER each page's inline styles so it owns the visual skin: a warm
   layered canvas (Craft-style color fields on cream) with frosted-glass
   surfaces floating above it. Pages keep their layout rules; this file
   re-skins the shared vocabulary (.card/.row/.note/.panel/header/buttons…).

   Accessibility commitments unchanged: Atkinson Hyperlegible body at 19px,
   ink on near-white glass ≥ 4.5:1, ≥44px touch targets, brick reserved for
   "Call for help", visible focus rings everywhere.
   ========================================================================= */
