Evolutions :

- Ajout d'icônes dans la scène, chapitre et arc
- Possibilité de bouger les cases dans la partie graphe et les textes associés si ces derniers ne sont pas visibles
- Changement sur le thème du graphe : mode sombre et plus blanc
- Barre d'action en haut, même pour la partie scène
- Mode sticky corrigé : plus de trou entre le haut du navigateur web et de la barre d'action

Passage version 0.6.5

+# Demo publique LoreMind
+
+Deploiement d'une instance de demo ephemere pour `loremind-demo.igmlcreation.fr`.
+
+## Principe
+
+Chaque visiteur recoit un environnement isole spawne a la volee, detruit apres
+un court delai d'inactivite. Les donnees ne sont jamais persistees.
+
+Le mode demo (variable d'env `DEMO_MODE=true` sur le core) masque les ecrans
+de configuration qui n'ont pas de sens en vitrine.
+
+## Deploiement
+
+Prerequis :
+- Reseau Traefik existant cote host
+- Images `core` et `brain` pushees au registre
+
+```bash
+cp .env.example .env
+# Ajuster .env
+docker compose -f docker-compose.infra.yml up -d --build
+```
+
+Premier build : 5-10 min. Suivants : incrementaux.
+
+## Mise a jour
+
+```bash
+docker compose -f docker-compose.infra.yml pull
+docker compose -f docker-compose.infra.yml up -d --build
+```
+
+Les sessions en cours sont tuees au redemarrage.
+
+## Observations
+
+- `docker logs loremind-demo-orchestrator -f`
+- `docker ps --filter "name=demo-"`
+
+## Desactiver
+
+```bash
+docker compose -f docker-compose.infra.yml down
+docker ps -q --filter "name=demo-" | xargs -r docker rm -f
+```
