Add a responsive login screen using the shared appearance controls and a browser-only customer-service simulator for the chat workspace. Register both routes and include mock media resolution, message sending, and earlier-history loading for interactive verification.
Register Lexical's English and Simplified Chinese catalogs in the application loader, import its global styles, and add the workspace dependency with its resolved lockfile graph.\n\nReplace the dashboard placeholder with a controlled rich-text editor demo that composes default actions, fixed and bubble toolbars, draggable blocks, generated HTML output, and reset behavior.
- replace the legacy client-only Vite bootstrap with TanStack Router routes, Start SSR, and Nitro output
- compose the reusable layout, navigation, appearance, chats, and notifications blocks with application-owned data
- persist UI preferences through server functions and initialize theme, sidebar, and breakpoint state before hydration
- add React Query, hotkey, toaster, and responsive dashboard integration
- add application-owned Lingui configuration and catalogs, mount the runtime provider, and lazily enable I18nDevtool in development
- remove superseded HTML, main entry, theme provider, and application ESLint configuration
