/* ============================================================================
   RailCompliant — design system  (railcompliant.com)
   FRA locomotive inspection, maintenance & compliance for heritage railroads.

   Direction: "builder's plate + signal cabin." A precise, official steel-and-
   brass identity that stays approachable. Three deliberate signatures:
     1. Signal-aspect status  — status pills borrow the railroad's own regulated
        colour vocabulary (green = clear, amber = approach/due, red = danger/
        overdue). The colour IS the meaning, not decoration.
     2. Monospaced regulatory data — locomotive marks, CFR citations, part
        numbers and audit hashes are set in a mono "data" face, like a stencilled
        number plate or a typewritten compliance form.
     3. Stencilled eyebrows — tracked uppercase labels evoke equipment lettering.
   System fonts only (strict CSP; no remote fonts, no CDN assets).
