   Las tapas no son fotos decorativas — el titulo y el autor estan impresos en
   los bordes, y object-fit:cover se los comia (las de 0.625 perdian ~6% de alto).
   Con contain se ve la tapa entera; las que no son 2:3 exactas dejan una franja
   lateral de pocos pixeles sobre el fondo del panel, que pasa desapercibida. */
