## 🚀 Quick Start (auth-service):

```bash
# Local development
cd services/auth-service
pip install -r requirements.txt
python main.py

# Test login
curl -X POST http://localhost:7011/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email": "user@daarion.city", "password": "any"}'

# Test /me
curl http://localhost:7011/auth/me \
  -H "Authorization: Bearer <token>"
```

**Mock Users:**
- `admin@daarion.city` → system_admin
- `user@daarion.city` → regular user
- `sofia@agents.daarion.city` → agent
