I need a thank you page that shows after successful Stripe payment:

Content needed:
- "Payment successful! Welcome to [Your Tool Name]"
- "Your monthly subscription is now active"
- "You have [X credits] to use this month" 
- Large "Start Using Your Tool" button linking to main app
- "Need help getting started? Check our quick guide" link
- Simple, clean design that builds confidence

Make it celebratory but focused on next steps. Customer just paid and should feel excited to start using the tool.

Please create this post-payment thank you page.
