/* ==========================================================================
   POS Fraud Monitor — Design Tokens & Shared Components
   Direction: a fraud/AML monitoring console — deep ink navy, teal for trust
   and primary actions, gold/orange/red reserved strictly for risk escalation.
   Data (amounts, masked cards, timestamps, codes) is always set in monospace
   with tabular figures — a ledger reads the same whether it's on paper or
   on screen, and analysts scan digit columns all day.
