/* ─── 1. SCHOOL / ABOUT PAGE: VIDEO HERO ────────────────────────────── */

/*
 * On desktop (≥992px): utility-bar and nav are position:fixed — they float
 * above the page flow with z-index 1040/1300. The hero starts at y:0 in the
 * flow so the video naturally extends behind the fixed nav band. The nav's
 * dark glass background blends into the video. Content inside the hero is
 * padded down by 130px so it reads below the nav.
 *
 * On tablet/mobile (≤991px): utility-bar is static, nav is sticky — both
 * sit in flow above the hero. No overlap; the hero starts below them.
