/* Detective Lumberjack UI.
 *
 * Design tokens live here as custom properties so light and dark differ in one
 * place. The chart series colours are a validated categorical palette: adjacent
 * pairs clear colour-vision-deficiency separation and every slot clears 3:1
 * against its own surface, in both modes.
 *
 * The Aiir brand colour #28C1DE is 2.15:1 on white, which is fine for washes,
 * focus rings and marks on dark surfaces but not for text or for thin lines on
 * white. Light mode therefore uses darker steps of the same hue where contrast
 * has to carry meaning, and the brand colour itself where it does not.
