/* Story 27.6 — front-door hero at `/`.
   Ported from the CEO-approved prototype
   (output/planning-artifacts/prototypes/front-door-hero-27.6.html): lights-on
   intro, spotlight rig, lifting platform, 3D logo with a roof flag, Option E front-squat
   links, chalk + random-move layers. Loaded after front-door.css and reuses
   its tokens; hero-only values are scoped to `.hero-stage`.
   Every hero class is prefixed `hero-` (the prototype's spotlight `.beam`
   once collided with the button's `.beam`); button internals are only ever
   selected under `.hero-lift`.
   Mobile-first: base rules target 360px, the 720px query scales up.
   CSP: styles are self-hosted, no web fonts (Barlow falls back as in 27.2). */
