+// A long clip in the feed plays as HLS from vmedia (a rendition the
+// connection carries, in pieces made as watched), and so does one too big
+// to play as it is (past 1080p: it used to wait for a tap); a short one as it is,
+// and a post linking an .m3u8 stream plays that. vmedia runs here for real,
+// on a local copy of the clip.
