    ⛔ IT IS PART OF THE CONTRACT, NOT AN EXTRA. `_page.py` and
    `_browser_context.py` both wrap the reply in `from_channel(...)`, so a
    server that answers `None` does not merely lose the handle - it raises
    `AttributeError: 'NoneType' object has no attribute '_object'` inside the
    client, on a call that otherwise worked. The first implementation here
    returned None and that is exactly what happened.
