- Replaced static paths with dynamic locale subpaths (`/[locale]/*`) in imports, URLs, and assertions across tests.
- Updated `next-intl` mocks for improved compatibility with `locale`-aware components.
- Standardized `page.goto` and navigation tests with `/en` as the base locale for consistency.
- **Authenticated Navigation:** Test header, footer, settings navigation, user menu interactions, and settings tabs for authenticated users. Validate logout and active tab highlighting.
- **Theme Toggle:** Add tests for theme persistence and switching on both public and private pages. Verify localStorage integration and DOM updates across scenarios.
