   el contenido de abajo no dé un salto al aparecer el anuncio. En escritorio se
   usa un creativo apaisado (tipo 970×90) y en móvil uno más compacto (320×100),

   Motivo real: en iOS Safari, cuando una imagen no carga (404), el "icono roto
   + texto alternativo" puede ignorar por completo el tamaño que le pusiéramos
   al <img> y crecer hasta ocupar cientos de píxeles (así se vio en un pantallazo
   real: una caja enorme en blanco con el icono roto arriba). Poniendo el tamaño
   en el contenedor — que no tiene ninguna imagen que pueda fallar — y colocando
   el <img> ABSOLUTO por dentro, el hueco no puede crecer pase lo que pase con
   la imagen. Además, `handleSponsorError` en script.js oculta el banner entero en
   cuanto detecta el fallo, así que ni siquiera debería llegar a verse el icono
   roto: esto es un cinturón de seguridad para el peor de los casos. */
