    Under ``CliRunner`` (no TTY) Rich derives its line width from the terminal,
    and that fallback diverges across the OS matrix and by terminal size — so an
    exact ``"..." in result.output`` assertion flakes whenever a message reflows
    at a different column (issue #1332; seen on ``test_login_multi_account``
    where ``"not overwriting"`` wrapped across a newline as ``"not\noverwriting"``
    in a narrow terminal). Forcing a wide fixed width removes the *incidental*
    mid-line reflow, leaving only the **authored** newlines in the source strings
    (the real render contract). The single shared ``console`` is reused by the
    services, ``session_cmd`` and the error paths, so pinning its size once
    covers every render site while still writing through to ``CliRunner``'s
    captured stdout. Patch ``Console.size`` at the class level so every shared
    console observes the same deterministic dimensions.

    ``rendering`` exposes a *second* console — ``stderr_console`` (a
    ``Console(stderr=True)`` for diagnostic/status output in ``--json`` mode) —
    and the ~15 CLI tests that assert on ``result.stderr`` reflow on its width
    the same way (#1410). Pin both consoles to the same wide, fixed dimensions
    so stderr assertions are as deterministic as stdout ones.

    this fixture re-pins the shared console to 80 columns on top of the autouse
    400-wide pin (pytest runs the autouse fixture first, so this inner patch
    wins for the test body), so truncation is exercised deterministically rather
