/* ==========================================================
   RATE FARM — DESIGN TOKENS
   A freight intelligence platform, not a brokerage site.
   Visual language: instrument panel, not marketing page.
   Dark navy base (matches existing brand), one blue accent,
   monospace used deliberately for data readouts — the
   report and sidebar should read like an engineering
   instrument, not a web form.
