// Tapping a video: in the feed it opens the media pager (feed-video-pager-
// test.js has the rest). In a thread, anywhere on the picture (not the
// player's own play button or control bar) goes full screen — the corner
// button is a reach on a phone. Full screen, a tap pauses a playing clip; a
// tap on a paused one comes back out. Taps on the controls stay the player's.
// Run: bun tools/video-tap-test.js
