     3. Screens & layout        8. Battle screen
     4. Buttons & controls      9. Overlays (game over, chat, modals, toasts)
     5. Title / menus          10. Desktop layout, reduced motion
   Performance notes: only transform / opacity are animated, there is no
   backdrop-filter, and blinking lights use stepped animations.
