   Portail LFPL : fond de nuit animé, tuiles de verre immobiles.

   Chargement (l'ordre compte) :
     1. assets/accueil.css        ← ce fichier (base + tuiles)
     2. agenda/agenda.css         ← inchangé (gabarit + agenda clair)
     3. assets/accueil-agenda.css ← surcharges sombres de la colonne

   Les variables de charte historiques (--marine, --line, --encre…)
   sont conservées telles quelles : agenda.css s'en sert pour ses
   fenêtres modales, qui restent volontairement sur fond clair.
