+## [Style] Page conversion CBR → CBZ — Simplification UI + notifications toast
+
+**Objectif :** Revoir le style de la page de conversion CBR → CBZ pour le simplifier, et remplacer le message statique "Conversion réussie" par les notifications toast de l'application.
+
+- [ ] Auditer le composant/template actuel de la page de conversion
+- [ ] Simplifier la mise en page (réduire la complexité visuelle, harmoniser avec le reste de l'UI)
+- [ ] Supprimer l'affichage inline "Conversion réussie"
+- [ ] Brancher les notifications toast existantes pour signaler le succès (et l'échec) de la conversion
