Regenerate types after configuration changes and use the selected environment's configuration. Follow the current TypeScript setup for the project's toolchain instead of hardcoding a generated declaration path or maintaining a handwritten binding interface. Types describe the expected bindings; they do not provision resources or prove the deployed environment is configured correctly.
