/*
 * web/css/call.css
 *
 * Layout + motion for the call screen. Everything on this screen is
 * stacked on top of the ambient background; when the remote video is
 * playing, the body toggles data-bg="hidden" to fade the background
 * away so we don't double-paint moving colour behind moving video.
 *
 * Key ideas:
 *  - .stage is the big area (peer video). Video is never stretched;
 *    .stage-backdrop is a blurred copy that paints letterbox bars
 *    when the peer's aspect ratio doesn't match the container.
 *  - .pip is the small self preview. Tap / swap exchanges it with
 *    the stage visually by toggling body[data-swapped]. The DOM
 *    doesn't move; only styles flip, so <video> elements never
 *    re-attach streams (that would drop frames and kill audio).
 *  - Header + footer auto-hide on inactivity. body[data-ui="hidden"]
 *    slides them off-screen via transform; tap/mouse revives them.
