+// A picture tapped in the feed opens in the media pager, on that picture:
+// swipes and arrows (all four) step through the feed's pictures, every one
+// of a post before the next post's. A tap on the picture that opened it
+// closes it, as before; once the reader has moved on, a tap shows the post's
+// details and the next tap (or Escape) closes the pager onto that post.
