+### Étape 44 — Refonte premium de l'espace responsable
+- Branche dédiée `style/responsable-premium-dashboard` créée depuis `develop`.
+- L'espace responsable adopte une structure de supervision distincte du parcours étudiant : barre supérieure métier, navigation latérale sur ordinateur et navigation compacte sur petit écran.
+- Dashboard enrichi avec disponibilités, emprunts en cours, retards, anomalies actives, notifications non lues, activité récente et taux de disponibilité du parc.
+- Accès directs ajoutés depuis les points d'attention vers les vues emprunts, stock, anomalies et notifications.
+- Les listes métier partagent désormais une hiérarchie visuelle, une recherche et des lignes responsives cohérentes avec la charte ENSUP.
+- Aucun changement backend ni métier ; rendu validé manuellement dans le navigateur et `dart analyze` sans erreur.
+
+### Étape 45 — Téléchargement CSV de l'historique responsable
+- Branche dédiée `feat/responsable-historique-export` créée depuis `develop`.
+- Client HTTP étendu pour récupérer un fichier binaire avec son type de contenu et son nom.
+- Le bouton `Export CSV` appelle désormais l'endpoint responsable avec l'identité simulée de Karim et déclenche le téléchargement navigateur.
+- Un état de chargement bloque les doubles clics et les erreurs API sont affichées dans l'interface.
+- Endpoint vérifié au runtime : réponse `200`, type `text/csv`, nom `historique-responsable.csv` et contenu non vide.
+- Vérification statique : `dart analyze` sans erreur.
+
+### Étape 46 — Refonte premium de l'espace étudiant
+- L'ordre actuel du parcours est confirmé : identification, puis choix `Emprunter` ou `Restituer`.
+- Branche dédiée `style/student-premium-workspace` créée depuis `develop`.
+- Charte et maquette conservées : couleurs ENSUP, typographies, barre supérieure, coins de marque et structure des écrans.
+- Barre supérieure rendue responsive, avec priorité donnée au titre et à l'identité sur les petites largeurs.
+- Accueil rééquilibré avec profil identifié, hiérarchie renforcée et cartes d'action adaptatives avec états de survol.
+- Catalogue, détail matériel et sélection de restitution enrichis sans modifier leurs données ni leurs actions.
+- Détail et checklists passent automatiquement de deux colonnes à une colonne sur écran étroit ; tableau de contrôle et lignes de matériel évitent les débordements.
+- Écrans de confirmation et de résultat conservés fonctionnellement et harmonisés via les composants partagés.
+- Vérification statique : `dart analyze` sans erreur.
