## Authentication

When auth is enabled, pass a bearer token on every request:

```bash
curl http://localhost:8080/v1/messages \
  -H "Authorization: Bearer <your-token>" \
  -H "Content-Type: application/json" \
  -d '{...}'
```

Auth is disabled by default. Enable it in `settings.yaml`:

```yaml
server:
  auth:
    enabled: true
    secret: "Basic <base64-encoded-user:pass>"
```
