## Structure attendue

- \`CLAUDE.md\` : mémoire active du projet
- \`AGENTS.md\` : symlink vers \`CLAUDE.md\`
- \`README.md\` : documentation projet
- \`.gitignore\` : exclusions Git de base

## Commandes utiles

\`\`\`bash
# Initialiser la mémoire projet
 gen-claude

# Démarrer la stack Docker
 docker compose up -d
