/* ============================================================
   AMERICAN PULSE — Design Tokens
   A civic data instrument. Sober, precise, non-partisan by design:
   blue/red are used only as literal party-data encodings, never
   as brand or decorative color. The brand accent is amber —
   a neutral "signal" color evoking gauges, dashboards, instrumentation.
