   CARD SYSTEM NORMALIZATION
   Reference cards: .cando-card (step 03) for layout + hierarchy;
   .arch-card (gate) + .app-card (step 08) for touch & feel.

   Locked system:
     • Container — 280px tall · 28px padding · 12px radius · 1px outline
     • Hover    — translateY(-3px) · frost border · surface-2 bg
                  · soft frost glow shadow
     • Top      — 48–52px tinted glyph/badge (or small mono tag pill)
     • Title    — 22px serif weight 600
     • Body     — 14.5px line-1.55, color ink-2
     • CTA      — bottom, dashed top border, mono 11.5px uppercase frost
