/* Pharoah dark house style (graphite and gold, as pharoahtechnology.co.uk), with a light variant.
   Colour reasoning, because the owner is colour-blind:
   - Result meaning is never carried by colour alone. Every verdict has a symbol (check, arrow,
     cross) AND a words heading AND a different left-border pattern, so it reads in greyscale.
   - The pass/stop pair is blue-teal against amber, not green against red. Those two stay far
     apart in lightness and hue for red-green and blue-yellow colour blindness alike.
   - Text on the dark panels is at least 7:1; on the light variant at least 5.5:1. */
