/* ===========================================================================
   HOME — the redesigned front-page surfaces: layered parallax hero, fact
   marquee, photographic category slices, annotated-jar editorial, kinetic
   manifesto, glowing closing CTA. Everything resolves from tokens.css +
   primitives.css; no brand literal lives here.

   Motion contract: base CSS renders every section complete and static.
   home.js (GSAP) only ADDS movement, and only when
   (prefers-reduced-motion: no-preference).
