// The media pager's buttons under a finger: the sound button mutes on ONE
// tap (the browser's click and the pager's pending tap both clicked it, so
// it toggled twice and a clip could not be muted — Adam, 2026-10-16), and
// the reaction button offers the emoji sheet, over the pager, as the feed's
// does; the emoji picked shows on the button, and a tap again takes it back.
