 ## Modifications réalisées
 
 - Migration des enregistrements d'événements internes depuis les anciens patterns jQuery `.bind()` / `.unbind()` vers `.on()` / `.off()`.
+- Modernisation des événements d'entrée pour privilégier Pointer Events quand ils sont disponibles, tout en conservant les chemins touch et souris en fallback.
 - Ajout de namespaces d'événements :
   - `.turn` pour les événements du livre et du document ;
   - `.turnFlip` pour les événements internes des pages pliées.

 ## What Changed
 
 - Updated internal event registration from deprecated jQuery `.bind()` / `.unbind()` patterns to `.on()` / `.off()`.
+- Modernized input events to prefer Pointer Events when available, with the existing touch and mouse paths kept as fallbacks.
 - Added event namespaces:
   - `.turn` for book-level and document-level turn.js events.
   - `.turnFlip` for internal flip-page events.
