 **Why a `children` block instead of flat routes?**
 
 Flat routes like `{ path: 'ai/assistant', component: ... }` would work for navigation but the URL structure would not be understood by the ng-matero sidebar. The sidebar resolves `route: "assistant"` relative to the parent `route: "ai"` — the routes file must mirror this nesting for the active-route highlighting to work correctly.
 
-**Why keep the backward-compat redirect?**
-
-Any bookmarks, Playwright tests, or external links pointing to `/ai-chat` will silently redirect to `/ai/assistant` without a 404 or broken navigation.

-Navigate to `http://localhost:4200/ai-chat` — it should silently redirect to `/ai/assistant`.
