/* =====================================================================
   HERMES design system

   Tokens are declared on :root for light and redefined under both
   prefers-color-scheme and [data-theme], so the platform follows the
   operating system by default and still honours an explicit choice.

   Colour is never the only carrier of meaning: every status badge pairs
   its colour with a text label and a shaped dot, so the interface remains
   readable to colour-blind users and in a printed briefing pack.
   ===================================================================== */
