/* =========================================================
   FORGE DIGITAL PARTNERS — Design System
   Concept: a "partnership ledger" — deal-making, not a dev portfolio.
   Ink-teal + brass/gold on warm paper. Serif display, grotesque body,
   mono for anything that reads like a deal term or data point.
