```

### Programmatic Usage

```python
from finopsmetrics.dashboard.iam_config_loader import get_config_loader
from finopsmetrics.dashboard.iam_system import get_iam_manager

# Create CFO from persona
loader = get_config_loader()
user_config = loader.create_user_from_persona('cfo_persona', {
    'user_id': 'user-cfo-001',
    'username': 'john.doe',
    'email': 'john.doe@company.com'
})

# Add to IAM system
iam = get_iam_manager()
user = iam.create_user(user_config)
```
