   JISETF — videos

   The page is a set of playlists, each built from one object: a
   player beside the list it plays from. The player starts as the
   video's own thumbnail and only becomes a YouTube player when it is
   asked to play (scripts/videos.js), so the page costs a few small
   images to load, not three copies of YouTube.
