/* ============================================================
   PaceMetrics — design tokens
   Palette: ink navy (#12172B), paper (#F7F6F2), brand indigo
   (#321DBA — carried over from the real PaceMetrics brand),
   warm ledger amber (#D98F3B), slate secondary text (#5B6472).
   Type: Fraunces (display) / IBM Plex Sans (body) / IBM Plex Mono (ledger labels).
   Signature: hairline "ledger" dividers with small mono eyebrow tags —
   a nod to the audit/lineage language used throughout the real content.
