Media pager: past the last slide, a "fetching the next video" screen — and the next one, when it comes, is moved onto. Adam reached the last clip before the next was in, and a swipe only nudged the clip and sprang back. Now the pager ends in a screen of its own: a ring sweeping round, three sparks orbiting the other way, the play mark (a picture mark in a pictures pager) breathing in the middle, and "Fetching the next video…" (or "Fetching more pictures…") with a sheen running through it, all still under prefers-reduced-motion. Landing there stops the clip left behind and asks for more at once (the feed pages on; the media grid's pager crawls); slides that arrive go in above it, and one arriving while the reader waits is moved onto and plays. With nothing older to be had (the feed at its end, or the media index), it says "That's everything for now" and goes still. The scroller no longer anchors (overflow-anchor: none), so a slide put in above the screen doesn't hold the screen in view. Strings in all 20 languages. tools/pager-tail-test.js (relays that take 3 s for anything older: the screen at the end, the clip behind stopped, the next clip moved onto and playing, the end saying that's everything, Escape onto the last clip's post); feed-pager-ahead and feed-media-views count slides without it.
