+# Éditeur visuel AccroCbio
+
+L'administration éditoriale fonctionne depuis **le frontend** : `http://ADRESSE-DU-SERVEUR:1028/admin` ou `https://votre-domaine/admin` (si nginx dirige cette URL vers React).
+
+L'URL `:1029/admin/` correspond toujours à **Django Admin**, un outil différent.
+
+## Première mise en route
+
+1. Installer / redémarrer les deux conteneurs avec le `docker-compose.yml` habituel.
+2. Dans le conteneur backend Django, exécuter `python manage.py migrate` (nouvelle migration `education/0003_sitecontent.py`).
+3. Créer un compte administrateur si nécessaire : `python manage.py createsuperuser` (ou utiliser un utilisateur Django existant avec `is_staff=True`).
+4. Ouvrir `http://IP:1028/admin` et s'identifier.
+5. Dans l'onglet **Pages**, choisir une page : le **mode édition** s'active automatiquement. Cliquer sur les petits crayons à côté des textes et sur **Changer l'image** près des illustrations. **Enregistrer** publie le changement, **Restaurer** remet la valeur par défaut.
+6. Utiliser les onglets **Ressources / Avis / Offres / Messages** pour créer, modifier, masquer et supprimer les éléments de la base.
+7. **Terminer** désactive les crayons ; **Tableau de bord** revient au panneau d'administration.
+
+## Informations techniques
+
+- Le frontend reste sur le port **1028** et le backend Django sur le port **1029** ; les fichiers Docker d'origine sont conservés.
+- Le `vite.config.js` transmet automatiquement `/api/` au service Docker `backend:1029`. En production derrière nginx, veiller à transmettre `/api/` à Django et toutes les routes du frontend, notamment `/admin`, à React.
+- Les images téléversées (PNG, JPG, WebP ; maximum 5 Mo) sont conservées dans `backend/media/editor/`. Sauvegarder ce dossier avec la base de données. Les liens HTTPS vers des images externes fonctionnent aussi.
+- Les textes modifiés sont enregistrés dans la table `education_sitecontent` (différentiel par rapport au texte du code). L'édition ne nécessite ni recompilation React ni redémarrage Docker.
+- Le mot de passe n'est pas stocké dans le navigateur. Le jeton d'accès est conservé uniquement durant l'onglet ouvert (`sessionStorage`) et est contrôlé côté API. Utiliser **HTTPS** en dehors du réseau local.
+- Les modifications des liens n'acceptent que les chemins internes (`/contact`) ou les URL HTTPS.
+- Le texte de la page et les illustrations peuvent être édités ; il ne s'agit pas encore d'un constructeur de sections glisser-déposer. Les composants React/shadcn et les mises en page restent définis dans le code.
+
+## Vérifications
+
+Tests Django (dans le conteneur backend avec sa configuration de test) :
+
+```bash
+python manage.py test education
+```
+
+Compilation du frontend :
+
+```bash
+npm run build
+```

+# Installation
+
+**Archive complète :** à extraire dans un NOUVEAU dossier, pas au-dessus de la production actuelle. Conserver un environnement et une base de données séparés.
+
+**Archive de modifications :** copier les fichiers `Site/...` au-dessus d’une COPIE du projet d’origine, puis supprimer les anciens fichiers indiqués dans `FICHIERS_SUPPRIMES.txt` si vous souhaitez nettoyer totalement le dépôt.
+
+Important : sauvegardez votre projet et la base avant toute intervention, et n’importez pas le `.env` de la boulangerie sans adapter `MYSQL_DATABASE`, secrets et hôtes. Aucun fichier `.env` réel n’est présent dans les ZIP.
+
+Les Dockerfiles et docker-compose.yml sont conservés tels quels. Seul `start.sh` a été modifié pour ne plus écraser le projet depuis l’ancien dépôt Git. Lire `README.md` pour configurer Django, MySQL et nginx.
+
+Contrôles effectués : syntaxe Python, analyse JSX/JS, résolution des imports locaux. Aucun build Vite ou test Django complet n'a pu être lancé ici, faute des dépendances npm/Python et d’une base de données disponibles dans le conteneur de travail.

+# AccroCbio — site React / Django
+
+Refonte éditoriale du site coursbiologiechaillou.fr, basée sur l'architecture `Site`.
+
+## Stack conservée
+
+- **Frontend** : React 19, Vite, Tailwind CSS 4, composants shadcn existants, port **1028**.
+- **Backend** : Django + Django REST Framework, port **1029**.
+- **Base** : MySQL 8 / MariaDB compatible, identifiants via `.env`.
+- **Docker** : `docker-compose.yml`, `frontend/dockerfile` et `backend/dockerfile` **inchangés**.
+- **Gestion du contenu** : Django Admin (`/admin/`) pour les PDF/liens, les avis, les offres et les messages.
+
+## Mise en place
+
+1. Utiliser **une nouvelle base de données**, distincte de celle du site de boulangerie. Ne pas pointer sur une base de production existante.
+2. Copier `.env.example` vers `.env`, renseigner les secrets forts et le domaine réel (`ALLOWED_HOSTS`).
+3. `docker compose up -d --build` (ou le script `start.sh` dans un conteneur Pterodactyl configuré comme auparavant).
+4. `docker compose exec backend python manage.py migrate`.
+5. `docker compose exec backend python manage.py createsuperuser` : il permet l'accès à `/admin/`.
+6. En production, placer le frontend et `/api/` derrière nginx sous le même domaine HTTPS. Vite preview/Django runserver restent des outils de développement : pour une exposition publique durable, préférer un serveur statique et Gunicorn.
+
+Les migrations insèrent des références à quelques **PDF déjà publics** (liens externes uniquement). L'auteur des documents et son hébergement gardent leurs droits. Il faut ajouter dans l'administration les PDF manquants dont le lien n'a pas été vérifié. Aucune archive PDF tierce n'est embarquée.
+
+### Ressources administrables
+
+- `GET /api/education/resources/?category=svt-premiere`
+- `GET /api/education/testimonials/`
+- `GET /api/education/announcements/`
+- `POST /api/education/contact/` (limite anonyme : 5 par heure par adresse IP, messages visibles depuis l'admin).
+
+La notification des messages par mail est facultative et s'active via `CONTACT_NOTIFICATION_EMAIL`, `EMAIL_HOST`, `EMAIL_HOST_USER`, `EMAIL_HOST_PASSWORD`, etc. Sans SMTP, le contact **est enregistré en base** mais aucun mail n'est envoyé.
+
+### Pages livrées
+
+Accueil, Présentation, Services à la personne, Avance immédiate, Ressources (SVT Seconde/Première/Terminale, BPH, SBM, STL Première/Terminale), Contact, Avis, Offre de rentrée, Mentions légales, Confidentialité.
+
+### Points à personnaliser avant publication
+
+- Renseigner l'hébergeur et valider les mentions légales / la politique de confidentialité.
+- Vérifier avec la propriétaire le droit d'utiliser le nom AccroCbio, les informations personnelles et les documents existants.
+- Confirmer la validité de toute offre avant de l'activer dans Django Admin (offre de septembre 2026 désactivée par défaut).
+- Définir une durée de rétention et un processus de purge pour les demandes de contact.
+- Configurer HTTPS, `ALLOWED_HOSTS`, SMTP si nécessaire, sauvegardes DB et éventuel cache partagé pour le throttling si plusieurs workers.
+
+## Tests
+
+- Backend : `python manage.py test education` (requiert les dépendances Python et une DB de test).
+- Frontend : `npm ci && npm run build`.
+
+## Sécurité
+
+Les fichiers `.env`, `.git` et les anciens modules de gestion de la boulangerie sont exclus de l'archive de distribution. Le modèle utilisateur personnalisé `users.User` et ses migrations sont préservés pour compatibilité avec l'ancienne structure de la base et l'administration Django.
