- `HtmlResponse` for JSP, `JsonResponse` for APIs

### Services
- Business logic in `app.service.*`
- Injected into Actions
- Use behavior classes to access OpenSearch

### Helpers
- Cross-cutting utilities in `helper.*`
- Stateless, injected via DI
- Access via `ComponentUtil.getFooHelper()`

## Development Notes

- **Code Style**: Enforced by `mvn formatter:format`
