6. Subscription activated automatically
7. User redirected to success page
8. Invoice generated and available for download

### Feature Access Flow
1. User tries to access a feature
2. Middleware checks active subscription
3. Middleware checks if plan has feature
4. If yes: Access granted
5. If no: Redirect with upgrade message

### Usage Limit Flow
1. User tries to create resource (campaign, content idea, etc.)
2. Controller checks current usage vs limit
3. If under limit: Resource created, usage incremented
4. If at limit: Error message, redirect to upgrade page
