/* generate.css — layout for the T4 screens: Progress, Result, Offline, and the

 * The Progress screen layers an AMBIENT holiday scene (drifting sun, clouds,
 * birds, a rolling wave) behind an honest, backend-driven progress bar. The scene
 * is decorative only — it fills the wait but never represents real progress. All
 * of its motion is neutralised by the prefers-reduced-motion rule in base.css.
