/* ============================================================
   Card "alive" interaction module (lcyoyo lesson sealed in v5)
   
   Why this exists: until r2, all card-class hover effects were just
   `border-color: var(--cyan)` — flat. The lcyoyo Redcoats Guide
   sites have a "card lift + shadow + accent border" pattern that
   makes the whole site feel alive. This module unifies that across
   every card class the factory generates, and adds the fadeUp
   hero-entrance animation lcyoyo uses on first paint.
   
   All effects use theme variables (--accent, --shadow-md, etc.) so
   they auto-adapt to retro-war / cyber-robot / night-sky-castle /
   dragon-fire and any future theme.
