   VENUS — HOME CINEMATIC HERO (Stage 5 · Phase 1.5 enterprise composition)
   Full-viewport, two-zone hero: typography LEFT, Material Stage object RIGHT
   (the object's screen position is set by the WebGL camera in home-cinematic.js,
   so it is never centred at 50%). Layered atmospheric background. Loaded only
   on the homepage. Progressive enhancement preserved (base static hero works
   without JS/WebGL/reduced-motion).
