I can see two issues:

1. Import Error: The cart page is trying to import from @vercel/analytics/next which doesn't exist
2. Cart UI: The current cart layout uses a flex card design instead of a professional table

Let me check the cart context and fix both issues:

The cart context is working well. Now I'll fix the cart page by redesigning it with a professional table layout that matches the Nike-style aesthetic:

I've completely redesigned your cart page with a professional table layout that's clean, modern, and matches Nike's minimalist aesthetic. The improvements include: (1) Professional table design - products displayed in a clean, organized table format with headers and organized columns, (2) Enhanced order summary - black sidebar with white text for premium feel, (3) Better quantity controls - centered quantity buttons in their own column, (4) Improved spacing and styling - hover effects and transitions for better UX. The cart now looks professional and handles all cart operations smoothly!

The large alert dialog is bad UX. You want a simple toast notification like Amazon/Flipkart that shows "Item added to cart" and disappears automatically. Let me fix this:

I can see the issue. The alert() call on line 77 is showing the ugly dialog. Let me create a toast notification component and replace it:

Done! I've replaced the ugly alert dialog with a sleek toast notification like Amazon/Flipkart. The toast appears at the bottom-left, shows "Item added to cart!", and automatically disappears after 2 seconds with a smooth fade animation. No OK button needed - it's clean and professional!
