   Strictly greyscale: no hue anywhere. Meaning is carried by solidity, line pattern, shape and weight.
   Light and dark follow the OS; the theme button overrides it. Every colour token is a light-dark()
   pair, so a region that sets `color-scheme: dark` (the imaging console, the footer) gets the dark
   values in both themes without a second token block. */
