 * adjacent colour-vision separation 9.1, normal-vision 22.9; slots 3 and 4
 * sit under 3:1 against the surface, which is why every chart keeps its table
 * and labels. Dark, on #14120F and #1C1917: worst adjacent 8.4 and 19.8, all
 * slots at or above 3:1. The dark steps are chosen for the dark surface, not
 * flipped from the light ones.
