/*
  Fletex — sistema de diseño "manifiesto de carga industrial".
  Oscuro, ámbar de seguridad vial como acento, tipografía stencil para la
  marca y monoespaciada para los datos (placas, kilometraje, dinero) —
  como una hoja de ruta o un manifiesto de carga real.

  Todas las clases/ids ya usados por el JS de panel-admin.html,
  dashboard-dueno.html e index.html se mantienen intactos; este archivo
  solo redefine su apariencia.
