/* MAGMA PALETTE: the third palette, the official Magma colormap.
 *
 * It is linked by every page with 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.
 *
 * Every accent is an exact entry of the colormap matplotlib publishes
 * (lib/matplotlib/_cm_listed.py, _magma_data): #000004 is entry 0, #51127c is 64,
 * #9c2e7f is 112, #ca3e72 is 140, #fc8961 is 192 and #fcfdbf is 255. The neutrals
 * are tinted towards the colormap's purple region, hue 306, because entry 0 is
 * black and carries no hue of its own. The semantic states keep their own colours
 * in main.css: a failure is not a palette colour.
 *
 * Magma runs from black to a pale yellow, so the light scheme's gradient ends in
 * #000004 and the dark scheme's in #fcfdbf: both ends are where this scale begins
 * and finishes.
 *
 * The matching favicon lives at favicon-magma.svg in the repository root.
