       binary so it never allocates a console.  Used as a fallback when
       ctypes is unavailable or ShellExecuteW returns an error code.
    3. **webbrowser.open** — stdlib last-resort fallback.

    ``os.startfile`` is intentionally omitted: it is another thin wrapper
    around ``ShellExecuteExW`` and therefore redundant with attempt 1.

    On non-Windows platforms this simply delegates to ``webbrowser.open``.
