Use the Next.js sample when you want a familiar web application setup with a clear path from standards-based login to a more structured identity layer.
The Next.js sample focuses on clean standards-based sign-in for a mainstream web stack. It does not pretend every real person is just an account record. Use it as the web entry point, then extend the product model only where managed profiles or delegated handling are actually needed.
These pages explain the sample on Tuurio's domain. GitHub remains the code host.
