/*
 * findkolonihave-statistik
 *
 * Colour is organised as two separate things, and keeping them apart is what stops
 * the charts from turning into a brand swatch:
 *
 *  - Brand colours dress the interface. The green from findkolonihave.dk, its dark
 *    green and its light mist appear on the header, the buttons and the focus rings,
 *    so the dashboard reads as part of the same site.
 *  - Chart colours are a separate, validated set. #72A656 only reaches 2.88:1 on
 *    white, so it is not safe as a mark; the series green is a slightly deeper step
 *    of the same hue. The brand orange is never a series colour at all: orange
 *    against green is the classic red-green confusion pair and measured ΔE 5.2 under
 *    simulated deuteranopia, well under the 8 target.
 *
 * Every chart value below was produced by the palette validator rather than chosen
 * by eye. Categorical is two slots because these charts never need more than two
 * (for sale against sold); both clear every check on all pairs in both modes. The
 * magnitude ramp is one hue, light to dark, which is the safe default for the
 * distributions and rankings that make up most of this dashboard.
