/* Sueldazo — estilos compartidos
   Idea: la boleta de pago peruana. El formulario es el "planillero" a la izquierda,
   el resultado se imprime como boleta a la derecha, con su sello y su borde troquelado.
   Una franja escalonada (motivo andino) en rojo marca la identidad, solo en la cabecera y los separadores. */
