/* ============ HERO (v2) ============
   Full-bleed motion video, Foldcraft-style left-aligned text, Forma-style glass nav.
   Palette: near-black ink world, off-white text, champagne gold #C9A96A as the
   single restrained accent (no orange). Vanilla CSS, transform/opacity only.

   Sources: research/21st-sources/ (liquid-glass-button, text-reveal) had not
   landed yet at build time, so no source was copied. Instead the glass recipe
   below is MOTION-SPEC 0.4 verbatim (itself the Forma/liquid-glass recipe:
   layered translucent gradient fill + masked luminous gradient edge +
   top light wedge + inset streaks, over backdrop blur/saturate/brightness),
   and the headline reveal follows the text-reveal pattern: overflow-hidden
   line masks, inner lines translateY(110%) -> 0, cubic-bezier(.22,1,.36,1),
   stagger per MOTION-SPEC section 2. The depth haze borrows the aurora /
   glow-horizon idea as a counter-parallax layer (data-speed -0.08), no filter
   blur on a full-screen layer. Floating elements are scene-native: two mini
   floating islets (generated art on pure black, screen-blended into the
   scene), plus one drift layer of CSS cloud wisps, an SVG bird flock and
   drifting motes. Transform/opacity motion only. */
