/* /vis: the palette and form the visualisations share.
 *
 * Unlike the rest of msge.no this family follows the reader's colour scheme,
 * light and dark, because a chart is read on whatever background the reader
 * chose. Tokens are declared on :root and redeclared for dark; nothing below
 * the token blocks names a colour of its own.
 *
 * The twelve --k-* category colours are /vis/mm's (design handoff v2). Each
 * category also has a two-letter code, and the code travels with the colour
 * everywhere (legend, badges, tiles, stack segments, table rows), so colour is
 * never the only cue. That is also what let the light steps be darkened: every
 * fill clears 3:1 on the light surface, and a code set on a fill in --on
 * clears 4.5:1, in both schemes. Measured pairs are in test/contrast.test.js.
 *
 * --graa is the faint text (section numbers, the "Anna" category), --rutenett
 * the hairline for grids and tracks. The tooltip inverts the scheme, which is
 * why it has its own three tokens. */
