/* image57.com marketing page — 2026-09-13 rebuild.

   A scroll-driven product page in the Apple-launch idiom: pinned scenes
   whose visuals advance with scroll position, reveal-on-enter copy, and a
   before/after slider in the hero. Everything is progressive: with JS off or
   `prefers-reduced-motion` on, every scene simply shows its finished state.

   Scroll state arrives as CSS custom properties set by site.js:
     --p   0..1 progress through a [data-scrub] scene
     --hp  0..1 how far the hero has scrolled away
     --pos 0..100 the comparison slider position
   Mobile-first: base rules are the phone layout; ≥ 820px adds columns. */
