/* Reloj Checador Grupo Carbon - estilos base
   Paleta alineada al logo oficial: negro + blanco, con ROJO como unico
   acento de marca (igual que la punta roja del icono del logo). Nada
   de azul/verde corporativo generico: blanco/negro es el protagonista,
   el rojo se reserva para lo que de verdad importa (acciones
   principales, estados activos, salidas/alertas). */
