/* Telbox landing — cinematic scroll narrative.
 *
 * 2026-05-19 (rev 2) — overhaul. Issues fixed: blank stretch in the
 * morning-problem act, text overlap during frame cross-fades, weak
 * motion, missing call-AI features act. Each act now has its own
 * visual world (brand register permission), with staggered reveals,
 * per-frame ambient washes, and stronger exponential ease-out.
 *
 * Palette mirrors apps/ios/Telbox/Theme/Theme.swift.
 * Legal pages use the same stylesheet via article.legal at the bottom.
