/* Corvernn homepage — one continuous scene (docs/public-site.md › Homepage). Hand-written; loaded only on `/`.
   Two modes share the same DOM:
   · FLOW (default: no JS, reduced motion, weak devices, very small heights) — every chapter is a normal section,
     every word visible, figures drawn once in their resolved state.
   · STAGE (html.nv-on) — the chapters are states of one sticky stage; home.js drives every visible property from
     visualProgress. Nothing in this file animates by itself in stage mode except hover/focus feedback. */
