Key Changes:
- Created Wrapper components (Fullscreen, Column, Container, ListedComponent) to standardize the application's overall layout.
- Refactored the structure of major components like App.tsx and PageContainer.tsx to use the new Wrapper components.
- Added a simple TodoBoard mockup page at the /todos route.
- Adjusted flexbox classes for the TodoBoard component to allow its width to resize flexibly based on screen size.
Replaces 'wouter' with 'react-router-dom' to standardize the routing library and resolve dependency conflicts.
Key changes:
- All routing logic, including hooks (useLocation) and components (Link, Routes), now uses 'react-router-dom'.
- The component tree has been simplified by removing the MainContainer component and moving its layout directly into App.tsx.
- The <BrowserRouter> provider is now correctly placed at the application's entry point in main.tsx.
