   thedenver.homes — MOTION SYSTEM
   Design recipes sourced from the 21st.dev catalog
   (Text Reveal Mask, Stacking Cards, Horizontal Scroll Gallery,
    Card Spotlight, Marquee, Count Up) and ported to dependency-free
    CSS + vanilla JS so the static Firebase site stays fast.

   PERF RULES (do not break):
   - Scroll-linked work only touches `transform` / `opacity`.
   - One rAF loop drives every scroll effect (see anim.js).
   - No layout reads inside the loop — geometry is cached.
   - Everything degrades to a static page under
     `prefers-reduced-motion: reduce` or when JS is off.

   21. THE BUILD — scroll-scrubbed WebGL section
   NOTE: sticky heights use svh, never dvh. On iOS the URL bar
   collapses during scroll, so 100dvh changes continuously — that
   resizes the pinned box and the WebGL buffer on every frame and
   makes the whole section judder. svh is the *small* viewport
   height and never moves. Any sliver left below the canvas shows
   the section's own background, which matches the scene.
   The canvas is pinned; copy panels cross-fade over it. Until
   scene.js reports in (html.build-live) the fallback grid is what
   renders, so no-WebGL / reduced-motion visitors still get the
   content with zero layout shift.

/* ============ 20. OFF-SCREEN ANIMATION PARKING ============
   The ambient loops here (hero aurora x2, footer aurora, coverage marquee,
   eyebrow sweeps) are all `infinite`, so before this they animated for the
   whole session — the hero's two aurora layers were still being recomposited
   every frame while the visitor read the footer. Each one is a promoted layer
   holding a large gradient texture, and the marquee additionally pinned
   `will-change:transform` permanently. On integrated GPUs that steady
   compositor load is what turns scrolling gritty.

   anim.js adds .anim-idle to a host section once it leaves the viewport.
   Pausing is free to reverse and visually invisible: an alternating 22s
   aurora resumes from the same phase, and nobody can see a marquee that is
   off-screen. Content animations (reveals, fadeUp) are NOT touched — they are
   one-shot and must be allowed to finish. */
