  Results: a contact sheet. One photo per cell (two-up when the sheet is wide enough, one
  full-width cell when there is one photo), each in a 2 px ink frame, with its controls set
  below as small uppercase chart rows using plain native inputs.

  The duochrome red/green appear here and nowhere else: the BEFORE/AFTER blocks (black
  letters on red and green, as on a real chart's duochrome panel) and the two edges of the
  compare divider.
