Let's fix the persistent white screen issue by focusing on the core files that are essential for the application to render. The problem is likely in the main entry points or router configuration.

I've made several important changes to fix the white screen issue:

Key Fixes:

1. Added Error Boundary: Added a simple error boundary in App.jsx to catch and display errors instead of showing a white screen.
2. Simplified Components: Created minimal versions of all required components to ensure the basic structure works.
3. Fixed Import Paths: Changed import paths to use relative paths (e.g., "../components/ui/card") instead of path aliases (@/components/ui/card) which might not be properly configured.
4. Added Console Logging: Added strategic console.log statements to help identify where rendering might be failing.
5. Added PostCSS Config: Added a postcss.config.js file which is required for Tailwind CSS to work properly.
6. Enhanced Vite Config: Updated the Vite configuration to include better error reporting and source maps.

Steps to Fix:

1. Replace the files with the simplified versions provided above.
2. Check your browser console for any errors after restarting the development server.

3. Install any missing dependencies:

   npm install react-router-dom@6.8.1
4. Clear your browser cache or try in an incognito window.

5. Restart your development server:

   npm run dev

If you still see a white screen, please check your browser's console (F12 > Console tab) and share any error messages you see there. This will help identify any remaining issues.
