/* Haruki — haruki.run
   Colour and type tokens mirror the app's own design system:
   app/src/main/java/com/haruki/run/ui/theme/Color.kt (2026-08 monochrome-chrome revision)
   and the Haruki Design System canvas.

   Rule of the system: the UI chrome is achromatic — unbleached paper and ink.
   Colour is lit only where it means something: the route actually run, the
   accumulation scale, and "now"/destructive. Nothing here is coloured for decoration. */
