I'll make these changes to improve the responsiveness and functionality of the application. Let's go through each modification:

These changes implement all the requested modifications:

1. Made all pages responsive and mobile-first by adjusting layouts and using appropriate CSS classes.

2. Updated the search layout in the RestaurantSearch component:

   • Moved the search button to the right of "Search Restaurants"
   • Moved "All prices" to the right of "All cuisines"
3. Implemented native camera access for QR code scanning on mobile devices in the ScanPage component.
4. Added a notification icon to the Header component, which is visible on all pages including the Home page.

The application should now be more mobile-friendly, have an improved layout for the Discover restaurants page, and provide a better user experience for QR code scanning on mobile devices.

Is there anything else you'd like me to modify or explain?

I'll investigate why you might be having trouble deploying the application and provide a solution. Let's go through the potential issues and fix them.

To address deployment issues, we need to check a few things:

1. Ensure all dependencies are correctly installed and listed in the package.json file.
2. Verify that the build process is working correctly.
3. Check for any environment variables that might be missing.
4. Ensure that the project structure follows Next.js conventions.

Let's start by checking and updating the package.json file:

Now that we've checked and updated these crucial files, here are some steps to try for deploying your application:

1. Make sure you have committed all your changes to your git repository.

2. If you're using Vercel for deployment (which is recommended for Next.js applications), follow these steps:

   • Log in to your Vercel account
   • Click on "New Project"
   • Import your GitHub repository
   • Vercel should automatically detect that it's a Next.js project and set up the build settings for you
   • Click "Deploy"

3. If you're using another platform or encountering issues with Vercel, try these steps:

   • Run npm run build locally to make sure there are no build errors
   • If there are any errors, fix them and commit the changes
   • Make sure all your environment variables (if any) are properly set in your deployment platform
4. If you're still encountering issues, check the build logs on your deployment platform for any specific error messages.

If you're still unable to deploy after trying these steps, please provide any error messages or specific issues you're encountering, and I'll be happy to help further troubleshoot the problem.
