/*
 * The status page look: the same neutral grayscale tokens as the Tillcast web
 * apps (web/ui/src/theme.css, OKLCH, shadcn names), with no brand colour. Status
 * colours appear only on small dots and always next to a word.
 *
 * The dark tokens are written twice because plain CSS cannot share them between
 * a media query and an attribute: the media block serves visitors who chose
 * nothing, the attribute block those who chose dark. test/theme.test.ts keeps
 * the two identical and checks the contrast of every pair in both themes.
