   FINANCEHQ — DESIGN SYSTEM
   Concept: "The Ledger" — ink & brass. Old-money bookkeeping meets a modern
   dashboard. Serif display for headline figures, tabular mono for money in
   tables, thin brass rule-lines borrowed from ledger paper as the signature
   structural device (used at section heads instead of generic card borders).
