/* Meridian design system — restrained, information-dense, WCAG-conscious.
   Colour is always a secondary cue: every coloured state also carries a

   contrast-tested in tests/test_visual.py (>= 4.5:1 on the plain surface AND
   on the tinted badge/chip backgrounds, in both themes). No external assets
   (CSP is self-only): all icons are CSS glyphs, all colours are variables. */
