   COMPEO — boot loader ("Golden Hour")
   Full-screen boot overlay for index.html only. A pure-SVG dusk scene
   warms as it loads; the sun sets, windows light up, then the overlay
   lifts straight into the site with the Compeo lockup revealed.
   Vanilla port of compeo-loaders-lab/src/loaders/04-golden-hour.
