/* ============================================================
   Cotizomatic — «la máquina de cotizar»
   Sistema esmalte retro (2026-08-08, orden de rediseño de los socios;
   supersede el monocromo del 2026-08-05 — ver DESIGN.md y DECISIONS.md).

   El mundo entero sale del render de la máquina Cotiz-O-Matic
   (02_MATERIALES/03_IMAGENES/hero-imagen-look-and-feel.jpeg):
     · crema esmalte   = el panel frontal (lienzo de la página)
     · teal esmalte    = el cuerpo de la máquina (paneles de control)
     · tinta cálida    = el texto grabado
     · rojo medallón   = el «O» del emblema (marcadores, UN acento)
     · cromo           = biseles de placas (filete, luz superior)
     · vidrio ámbar    = el visor interno (SOLO el odómetro y /app)
   La página se compone como hoja de especificaciones / manual de
   instrucciones de mediados de siglo: marcos impresos, FIG. numeradas,
   placas grabadas, tickets que la máquina imprime.
