/* ---------- Reveal on scroll ----------
 *
 * JS adds .reveal to .hero and every section[id] as soon as it runs, then
 * toggles .is-visible either on load (hero) or when the element crosses the
 * IntersectionObserver threshold (sections).
 *
 * Curve matches the anchor-scroll easing: cubic-bezier(0.22, 1, 0.36, 1) is
 * the "expo-out" deceleration curve -- fast arrival, soft settle. Same
 * perceptual family as the JS `1 - (1-t)^5` used for scroll, so the two
 * animations feel like they came from the same system.
 *
 * Duration 700ms is in the Material "medium" band and matches enterprise
 * restraint -- long enough to read as intentional, short enough not to drag.
