I'll update the copy button to provide better visual feedback and user experience.

The updated copy button now includes:

1. Visual feedback: Changes color and shows a checkmark when successfully copied
2. Better animations: Smooth transitions and hover effects
3. Auto-reset: The success state automatically resets after 2 seconds
4. Error handling: Properly handles copy failures
5. Improved accessibility: Dynamic tooltip text that changes based on state
6. Enhanced UX: Scale animation on hover for better interactivity

The button will now clearly indicate when the copy action is successful with a green checkmark and different styling.
