/* Quire — design system
   Source spec: blueprint-clean SaaS. Two-tier surface (mist canvas, white
   cards), one saturated accent reserved for filled CTAs, hairline borders
   instead of shadows, and aggressively tightened display tracking.
   Buttons are 12px — never pills. Cards are 8px.

   Token NAMES are held stable from the previous system so the palettes in
   assets/themes/ keep working; only their values and the rules below changed. */
