/* ============================================================
   BEANLEAF — HERO
   Full-bleed sunlit sky. The WebGL scene (js/hero-scene.js)
   paints on .hero-canvas; the CSS gradient underneath matches
   it stop-for-stop so there is no flash before first paint.

   Layers:  1  .hero-canvas   (WebGL sky, clouds, the two cups)
            2  .hero-fallback (CSS-only composition, no-WebGL)
            3  .hero-inner    (the copy column)
            4  .hero-scroll

   Colour: tokens everywhere except the sky ramp's two intermediate
   stops and the rgba() gradient stops, which need an alpha channel.
   Those rgba triples are tokens spelled out:
     255,255,255 --porcelain   252,251,248 --paper
     247,243,236 --linen       243,247,242 --mist
     233,239,225 --tea-wash     30, 42, 34 --ink
   ============================================================ */
