/* broadcast-player.css — shared Netflix-style live broadcast player
 *
 * Sizing strategy (YouTube theater-mode approach):
 *   - Width: 100% of parent
 *   - Height: derived from width (56.25vw = 16:9) so aspect ratio is always perfect
 *   - max-height: clamped so it doesn't consume the viewport on wide/short screens
 *   - On ultrawide: player shrinks height, width auto-adjusts via max-width = height * 16/9
 *   - This avoids object-fit:cover cropping the broadcast frame
 *
 * Layout: --bp-header-h controls header offset (default 0px)
