v3: youtube playlists get a tracklist too — the embed keeps playing the list, so the rows come from two halves: /api/youtube/playlist scrapes titles and lengths off the playlist page (current lockup rows and the older renderer, cached 6h), while the IFrame API attached to the iframe reports the position and takes row clicks and ⏮/⏭; the header names the playing video with the dump's title below it, like a bandcamp track; either half can fail — no scrape leaves the bare embed, no API leaves the rows as a table of contents — and the pause an API-enabled embed gives itself when the tab goes to the background is undone within a short window, so a later pause still stands
