   UPROH — Site public · système « Liquid Glass »
   --------------------------------------------------------------------------
   Une université avant une interface : de grandes surfaces claires, une
   typographie académique (Playfair Display + Inter), des photographies en
   pleine largeur, et le verre réservé aux éléments qui flottent au-dessus
   d'une image — menu, boutons du héros, légendes, appel final.

   Le flou (`backdrop-filter`) ne s'emploie que là où une image passe
   dessous : sur fond uni il ne se verrait pas et coûterait quand même. Sans
   prise en charge, ou si l'utilisateur demande moins de transparence, le
   verre devient une surface pleine de même teinte.
