Pour identifier les re-renders, utilise `React.memo` avec un comparateur personnalisé plutôt que `React.memo` par défaut : cela évite des re-renders inutiles sur des props d'objets créés à chaque rendu parent. Pense aussi à stabiliser les callbacks avec `useCallback` en listant les dépendances minimales.
