/* VIRIDIS PALETTE: the default, the official Viridis colormap.
 *
 * It is linked by every page right after main.css, beside the other palettes,
 * and exactly one of them is on at a time: the footer switch turns one on and the
 * rest off, and the pin script in the layout has made that choice before the
 * first paint. The rules are unlayered, so they beat the layered tokens in
 * main.css no matter the order the files arrive in.
 *
 * Every accent is an exact entry of the colormap matplotlib publishes
 * (lib/matplotlib/_cm_listed.py, _viridis_data): #440154 is entry 0, #3b528b is
 * 64, #26828e is 112, #fde725 is 255 and #5ec962 is 192. The neutrals are tinted
 * towards the colormap's dark end, hue 280 in the light scheme and 300 in the
 * dark one, and the semantic states keep their own colours in main.css: a failure
 * is not a palette colour.
 *
 * The matching favicon lives at favicon.svg in the repository root.
