Error Handling Strategy

1. User Feedback:

   • Use Toast Notifications (sonner or use-toast) for all user actions.
   • Success: "Item added to cart." (Green)
   • Error: "Failed to checkout. Insufficient stock." (Red)

2. Component Failures:

   • Create error.tsx files in route segments to catch server errors without crashing the whole app.
   • Use not-found.tsx for 404s (e.g., Product not found).
