* <li>Determine the OS family (e.g., Windows, Unix, Mac)</li>
 * <li>Check if the current OS is Windows-based</li>
 * </ul>
 * <p>
 * The service implementation uses system properties to detect OS characteristics:
 * <ul>
 * <li>os.name: The operating system name</li>
 * <li>os.arch: The operating system architecture</li>
 * <li>os.version: The operating system version</li>
 * </ul>

Deste modo, ao utilizar `secrets.compare_digest()` no código de sua aplicação, ela estará a salvo contra toda essa gama de ataques de segurança.

O programa de linha de comando chamado `fastapi` é o **FastAPI CLI**.

O FastAPI CLI recebe o caminho para o seu programa Python (por exemplo, `main.py`), detecta automaticamente a instância de `FastAPI` (comumente nomeada `app`), determina a forma correta de importação e então a serve.

Para produção, você usaria `fastapi run`. 🚀
