+  - Error messages if failed
+- `Task` model in database for logging
+- `GET /api/v1/journal/:date/tasks` endpoint
+- `GET /api/v1/tasks/:id` endpoint
+- **Theme System**: Light/Dark/System theme toggle
+- **Branding**: "DearDiary.io" logo in navbar
+
+### Changed
+- **Renamed project from "TotalRecall" to "DearDiary"**
+- Journal generation now returns `{ journal, task }` on success
