/* Sedum eval dashboard.
 *
 * Colours come from the validated reference palette: one categorical hue (blue,
 * slot 1) carries every rate, because every rate on this page is one series and
 * a second hue would imply a distinction that is not there. Behaviour outcomes
 * are labelled numbers rather than a stacked three-colour bar — the status
 * triple does not clear CVD separation when three of them sit adjacent, and
 * three labelled numbers read better than a 40px stack anyway.
 *
 * Status colour appears only as a dot beside a word that already says the same
 * thing, which is the documented mitigation for a status hue carrying meaning.
