// Pictures in a quoted post are in the pager too. A post quoting another
// draws the quoted one inside it; a tap on a picture there opened it alone
// (the pager's list held only the feed posts' own pictures), with nothing to
// swipe to. Now a post's row in the pager has, after its own pictures, those
// of the posts it quotes: left and right walk them, down goes on to the next post's, the
// quoted picture's details name its author, and closing lands on the post
// that quoted it.
