   COMMENT PERSONNALISER RAPIDEMENT :
   1) Change les couleurs, polices et espacements dans le bloc
      ":root" juste en dessous — tout le site suit automatiquement.
   2) Les textes se modifient dans index.html.
   3) Les photos se remplacent dans le dossier /images (voir les
      classes .img-placeholder pour savoir où les insérer).
