// In the installed app (no address bar: the pager already fills the window)
// the pager doesn't go full screen — every time it did, Chrome put up its
// "To exit full screen…" notice. Nor is the screen turned for a wide clip
// (it plays with bars). In a browser tab it goes full screen as before
// (feed-video-pager-test). A feed clip's own bar has no full-screen button:
// a tap on the clip is the way, into the pager.
// Run: bun tools/fullscreen-notice-test.js
