   THREE COLORS ONLY:

     PRIMARY    Gold     #C9A961   (brand · active · featured)
     SECONDARY  Slate    #334155   (structure · text · default)
     TERTIARY   Slate-400 #94A3B8  (low-emphasis accents)

   Plus white and a slate-tinted neutral scale.

   All status colors (success/danger/warning/info) are remapped to
   slate intensity variants. Differentiation comes from FILL
   (solid vs ring), WEIGHT (bold vs regular), and PLACEMENT —
   not hue.
