// A post whose clip its host no longer has (deleted from Primal's blossom:
// a 404 with no CORS headers, which the probe can't read) sat in the feed
// as a dead player under "Tap to play" that did nothing when tapped —
// "Video in this post won't play" (Adam, 2026-11-01). The player is the
// first to know the file is gone: it now says so where it stood, with the
// file's link, its controls and cover gone; the next paint of the post says
// it at once, with no request. A clip on a live host plays as before.
