   La figura del proceso, que es la que fija el tamaño: las diapositivas van en posición absoluta

   Antes era 4/5 vertical y sin tope: a 1440 px la columna mide 666 px, y 4/5 la estiraba hasta
   **833 px**, casi la pantalla entera. Además, las cuatro fotografías del proceso son 1,5 · 0,67 ·
   1,33 · 1,0, y meterlas todas en un marco vertical obligaba a recortar hasta el 47 % del ancho de
   las apaisadas.

   Con 4/3 y un tope de 480 px el marco queda en 666×480 (1,39) y el recorte máximo baja a la mitad.
   El tope se aplica en todas las anchuras a propósito: a 768 px el marco pasaría a 512 px, y
   limitarlo a 480 mantiene la misma regla sin convertirlo en una franja de 2:1.
