   enhancements.css — modern polish + motion layer
   Loaded LAST (after style.css + cyber-theme.css), so it refines without
   replacing anything. Two goals:
     1. Make LIGHT mode feel clean & premium (soften the dark-oriented glows
        and black shadows that cyber-theme.css applies to every theme).
     2. Add tasteful, user-friendly motion (staggered entrances, smooth
        hovers, animated theme toggle) — all gated by prefers-reduced-motion.
   Safe to remove: delete the <link> in index.html to fully revert.
