   WISE — Design System Tokens

   ------------------------------------------------------------
   Single source of truth for color, typography, spacing,
   radius and elevation tokens.

   FONT SUBSTITUTION NOTE
   Wise Sans is proprietary and not redistributable. This system
   substitutes:
     • Display (weight 900) → Manrope 800 (geometric, heavy)
     • Sub-display + body     → Inter (the brand's actual 2nd face)
   Swap in real Wise Sans @font-face files under /fonts when
   licensed; keep the --font-display var pointing at it.
