   ANIMATION CONTROL
   The scene (clouds/water/character/birds/leaves/fireflies) and the
   Critical-task pulse both loop forever by default. Two independent
   guards keep that from burning CPU/GPU when it isn't buying anyone
   anything:
   1. prefers-reduced-motion — respects the user's OS-level motion
      setting. The Critical pulse still needs to *read* as urgent
      without moving, so it gets a static ring instead of no signal.
   2. .anim-paused (toggled by animation.js via visibilitychange) —
      freezes everything while the tab is in the background, since
      an off-screen animation can't be seen and shouldn't be costing
      anything. This is independent of the --anim speed slider in
      Settings, which still controls speed whenever motion does run.
