   THE PLATE
   ------------------------------------------------------------
   One 3:2 image can't fill a tall phone screen: `cover` crops the
   logos away, `contain` shrinks it to a strip. So bg.png is drawn
   twice and each copy is cropped by its container to just the part
   that matters — logos pinned to the top edge, wave pinned to the
   bottom edge. The flat field (--paper) covers everything between,
   and the joins are invisible because that field is a solid
   #dbdbdb right across the plate.
