I've created a modern, user-friendly payment modal that:

1. Matches your dark theme and design system
2. Features smooth transitions and hover effects
3. Shows clear pricing information
4. Has proper loading states
5. Includes payment method selection with logos
6. Uses radio buttons for clear selection
7. Shows selected plan details
8. Has proper error handling structure

Key features:

• Clean, organized code structure with separate components
• Type-safe with TypeScript
• Responsive design
• Accessible with proper ARIA attributes
• Reusable components
• Easy to maintain and extend

The modal appears when clicking any "Get [Plan]" button and provides a seamless payment method selection experience. Let me know if you'd like any adjustments to the design or functionality!
