/**
 * About Us Page
 *
 * Clean, edge-to-edge layout that fills every screen.
 * The video is the hero — it gets ALL remaining space.
 * Scrolls gracefully when zoomed or on very small screens.
 *
 * Flex chain:
 *   .about-container (fixed, flex column, full viewport, overflow-y auto)
 *     .video-focus-section (flex: 1 — fills remaining)
 *       .video-focus-inner (flex: 1, flex column)
 *         h1                  (flex-shrink: 0)
 *         .video-intro        (flex-shrink: 0)
 *         .video-wrapper      (flex: 1 — VIDEO FILLS THIS)
 *           .video-container  (aspect-ratio 16/9, max-height 100%)
 *         .video-progress     (flex-shrink: 0)
 *     .post-video-cta         (flex-shrink: 0 — fades in after video)
 *     .about-footer           (flex-shrink: 0)
