/* Ferretería Beypaz — kit de marca y sistema de diseño
   Colores tomados del logo (public/img/logo.png):
     Verde bosque  #063c1e  contornos y "FERRETERÍA" → estructura (barra lateral, encabezado, acceso)
     Verde Beypaz  #0c843c  cerchas del techo        → acción principal, enlaces, gráficos
     Verde lima    #a6c83a  brillos de las cerchas   → detalles y realces sobre fondos oscuros
     Amarillo      #f8d810  letras "BEYPAZ"          → acento: sección activa, foco del escáner, destacados
     Oro           #e8b818  sombra de las letras     → acento sobre fondos claros (mejor contraste que el amarillo)
   El logo siempre va sobre una placa blanca (.brand-plate): sus contornos y "FERRETERÍA" son verde bosque
   y desaparecen sobre fondos oscuros. El rojo se reserva para alertas de stock.
   Sin fuentes externas: funciona sin conexión. */
