   UNDEAD ARENA — MOBILE OPTIMIZATION LAYER
   Dimuat paling akhir (setelah styles.css & modern.css) agar dapat
   menormalkan ukuran / spacing / touch-target untuk perangkat mobile.

   Struktur:
   0. Token & safe-area
   1. Global anti-overflow
   2. Touch target & tap behaviour
   3. Form (anti auto-zoom iOS)
   4. Modal -> bottom sheet
   5. Header & navigasi
   6. Layout landing (hero, stats, grid)
   7. Dashboard, sidebar, bottom nav
   8. Bracket & tabel scroll
   9. Kartu, list, media
   10. Utilitas & landscape
