 - **Sidebar profile was heavy card** — background, border, shadow. Fix: flat row with thin separator.
 - **Custom icons too thick** — Lucide 1.5px at 16-19dp looked chunky next to W300 text. Fix: 7 custom `ImageVector` icons at 1.0px stroke in `KaizenCustomIcons.kt`.

+- **Locked chat title leaked via search** — sidebar search matched against the real `item.title` of locked chats. Fix: locked chats excluded from search results.
+- **"Titel generieren" available on locked chats** — generating a title is a form of renaming and shouldn't work on locked chats. Fix: blocked in 3-dot menu (same as rename).
+- **"Duplizieren" available on locked chats** — created an unlocked copy with all messages, completely bypassing the lock. Fix: blocked in 3-dot menu.
