/* ===== Full-screen player: flat controls on a live cover-colour background =====
   Replaces the glows, pulse ring and equaliser-in-the-button of style.css; the background is three soft colour
   fields drifting back and forth (transform/opacity only, so the compositor does the work), kept away from the text.
   Loaded after ui.css; every rule is scoped to #player-full. Layout rules that differ per screen are in
   three blocks: phone portrait (default), phone landscape (short), desktop (>= 1024px keeps its own grid). */
