Console.WriteLine(ok);                      // True
Console.WriteLine(iban.Value!.Value);       // FR1420041010050500013M02606

Contributing

See contributors.md for guidelines. In short, fork the repository, create a topic branch, and open a pull request:

1. Describe the motivation and design in the PR description.
2. Ensure tests and formatting checks pass.
3. The maintainers will review and merge when ready.

Continuous integration via GitHub Actions restores dependencies, builds, and runs the test suite on every push and pull request. Packages are produced by the publish workflow and releases are drafted automatically.
