/* «Колечки» landing (/). STUDIO_SPEC §2–§3. Tokens: src/ui/theme.css, re-tinted here for the landing only.
   Components come from src/ui/kit/kit.css (@layer kolechki.kit); this file is unlayered, so it wins where it must.
   Structure: header · hero (one pinned screen) · facts band · showcase strip · ribbon · try-on · three steps · finale
   · footer · phone sticky CTA. 3D acts are transparent over ONE fixed canvas (#stage); the strip, the ribbon and the
   first-screen poster are baked renders of the same engine (assets/thumbs). Without WebGL (html.no-3d) the scene
   boxes collapse. */
