The most themeless theme ever themed. Grayscale, derived rather than chosen.

Palette is computed by ranking the eight ANSI hues by Rec.709 luma.
Every ink slot measured against #121212, worst
first. A slot marked exempt sits below the floor deliberately and says
why on hover.
All 5 of them, drawn by
tools/make-palette-untitled. Re-run it and
you get a different set in the same palette, because the recipe is what ships.
