/* UptimeNorth — Cabin Plaid. Brand v3.0, September 2026.
   Two layers of colour:
     1. the fixed brand palette, which never changes — mirrors brand/tokens.json
     2. role tokens, which flip between the light (default) and dark themes
   Components only ever reference role tokens. Change the palette in
   brand/tokens.json and here together. */
