   ALLÉGEMENT MOBILE & APPAREILS MODESTES

   Trois familles d'effets coûtent cher sur un GPU de téléphone :
     - backdrop-filter : recompose la zone derrière l'élément à chaque image
     - filter: blur()  : idem, sur de très grandes surfaces (les halos)
     - mask-image      : recalculé au défilement
   On les retire ici. Le rendu reste fidèle : les fonds translucides sont
   remplacés par des aplats de teinte équivalente.
