   Medido: en la ficha del curso de 999 EUR tapaba el boton de compra (el boton
   iba de 498 a 543 px y el banner empezaba en 465). Un banner de cookies que
   tapa el boton de comprar es, ademas de molesto, dinero perdido.

   Lo que NO cambia: ni una palabra del texto, ni el orden de los botones, ni la
   facilidad de rechazar. Al contrario: "flex: 1 1 0" les da a Rechazar y
   Aceptar exactamente el mismo ancho, asi que rechazar pasa a ser literalmente
   igual de facil que aceptar, no solo "parecido". */
