   ESA ARCADE - Shell, ambient, transitions, welcome, intro, play + HUD.

   tournament screens in css/tournament.css.

   GAMEPLAY RULE: body.is-gameplay freezes every decorative animation
   (ambient, dust, bezel bulbs, CRT, mascot). Only the game and its HUD move.

   V4.1 PERFORMANCE
   1. Inactive screens are only visibility:hidden (they must keep their
      layout for measuring), so their infinite decorative animations
      (arrow nudges, idle bobs, bulbs, breathing faces) used to keep
      ticking behind whatever was on screen - including behind gameplay.
      They now pause while their screen is not the active one.
   2. Adaptive quality (js/quality.js): body.q-medium / body.q-low trim
      DECORATION only - never anything a game reads.
