"""Create a Console that emits plain text when stdout is not a TTY.
Rich's spinner, Live render, and cursor-visibility escape codes all
key off ``Console.is_terminal``. Forcing ``force_terminal=True`` overrode
the ``isatty()`` check and caused control sequences (``\\x1b[?25l``,
braille spinner frames) to pollute programmatic consumers such as
``docker exec -i`` or pipes, even with ``NO_COLOR`` or ``TERM=dumb``.
Deferring to ``isatty()`` keeps Rich output in interactive terminals
and plain text everywhere else (#3265).
