     CTA · acero pulido
     Un botón casi blanco sobre grafito es el elemento de mayor
     contraste posible (16:1): no necesita color para gritar
     "acá se hace clic", y no compite con ninguna marca del catálogo.
     El degradado + el filo interior superior son lo que lo saca
     de "rectángulo gris" y lo llevan a "metal pulido".

     Si querés volver a un CTA de color, son estas líneas y nada más.
