/* ---------- Leaf-fall scroll-scrub video (site-wide, purely decorative) ----------
   Fixed, full-viewport, sits behind all real content. Hidden until the user
   scrolls past the hero (js/main.js toggles .is-active), then its currentTime
   is driven directly by scroll position — the video itself never plays.
   Content panels above it (section-alt, cards, etc.) stay opaque or get a
   translucent off-white so text remains fully legible; see the section rules
   below for how each section reveals or dampens the layer. */
