 * GlassCard — Boff UI 2.0 surface primitive composed over the base Card visual

 * hero/metric/insight surfaces while staying on semantic tokens only.
 *
 * No-movement policy: cards NEVER shift position on hover. Hover only
 * intensifies the shadow/border (a calm highlight) — it never translates,
 * scales, or removes the resting shadow. Reduced-motion / high-contrast
 * collapse the glass + glow via the underlying tokens.
