   A monitor-pixel field: square "pixels" everywhere, with the logo's "Ad"
   resolving out of them in the bottom-right corner. The mark is
   assets/img/footer-mark.svg — the mark.png tile sampled onto a 46×46 grid,
   one <rect> per lit cell (regenerate with scratchpad/mosaic.swift).

   ROLLBACK: delete the two rules below and un-comment this block — it is the
   previous generic dotted halftone, unchanged.
