A thumbnail used to try the provider and only ask /api/image once that had failed, so every hotlink-blocked host cost a wasted request per card before anything appeared. Both routes now go out together for the first thumbnail of a host, and the rest of the batch waits on that one answer rather than each rediscovering it. Speed decides which image is shown; capability decides what the host is remembered as, since the proxy tends to win first contact merely for being same-origin -- pinning a host to it over that would push a whole page of thumbnails through our own server. Playback asks the same question, but per video and at play time: one provider can spread its media over several CDNs, so there is nothing useful to pre-compute, and the old per-card probe answered for whichever card happened to scroll past. The direct route is now tested alongside the proxied playback and takes over if it answers before a frame is decoded. Whatever loses is cancelled -- the token guards stopped stale callbacks but left their requests running, so the losing route kept pulling bytes and the server kept an upstream connection open for them.
