- `@Secured({ "role", "role-view" })` for authorization
- Return `HtmlResponse` for JSP, `JsonResponse` for APIs

### Service
- Inject behaviors (Bhv) for data access
- Use `OptionalEntity<T>` for nullable returns
- Plain classes (no extends/implements)

### Helper
- Stateless utility classes
- Access via `ComponentUtil.getXyzHelper()`
- Named with "Helper" suffix

### DBFlute Generated Code
