/* Spoed Sleepdienst — the intro film (DOM is built by assets/js/flight.js; locked play-through intro)
 *
 * Contract (see _bron/CONTRACT.md "Intro"):
 *  - #flight is exactly one viewport tall (flight.js pins the px height from the stage's 100svh) and holds the stage
 *  - flight.js sets --flight-p (0..1) and --flight-overlap (px) on <html>, html.flight-lock while the intro owns the
 *    page, html.flight-done after the film ended or was skipped
 *  - A's #hero rises over the frozen last frame with margin-top: calc(-1 * var(--flight-overlap, 100svh)) and needs
 *    main#site{position:relative;z-index:2}. While html.flight-lock the stage is lifted ABOVE #site (z-index 60) so
 *    the Skip / Bel direct buttons and a tap on the film receive real clicks; A must additionally set
 *    html.flight-lock #site{pointer-events:none} and hide the header with visibility (never `inert`).
 *  - poster / video / final still share one framing: absolute, inset 0, object-fit cover, NO transforms
 *  - hidden things use opacity/visibility + pointer-events — never `inert` on a full-screen layer (it freezes scrolling)
 *  - stage background is the site's asphalt black, so nothing ever flashes white
