/* Overpass dashboard styles (master plan §12).
   Colour tokens live in three authoritative theme blocks: :root (light),
   :root[data-theme="dark"], and :root[data-theme="contrast"]. web/contrast_test.go
   parses these blocks and fails any text pair under 4.5:1 or icon/large-text pair
   under 3:1. Accents are blue (pass) and orange (fail) — never red against green;
   status is always icon + text, and shapes differ per status. */
