/* =================================================================
   VRP Trading Framework — Operations Dashboard
   Theme tokens come from a validated data-viz reference palette.
   Status hexes (good/warning/critical) are mode-invariant; the two
   "info" hues get a dark step. State is ALWAYS shown as accent +
   dot + label, never color alone.
