/* Color-separated overlay compare:
   1. Black-line plans are inverted to white-line on black.
   2. Each layer is tinted by combining "brightness(0) saturate(100%)
      invert(...)"-style filters, but the simplest reliable approach
      is mix-blend-mode:screen + drop-shadow tint using a colored
      tile overlay.  We give each plan its own colored tile and
      mask it by the inverted image via blend modes.  The third
      (difference) layer highlights pixels that disagree.           */
