## Description Overviews are shared between terminal help and rendered docs, so app authors write them with Sphinx markup. In plain terminal help that markup showed literally, e.g. an overview containing `:doc:`the tutorial <tutorials/index>`` or a `.. note::` block rendered the raw Sphinx syntax in the terminal. Like the existing double-backtick stripping from #306, this removes Sphinx markup from plain help only: - Roles `:role:`text``, `:domain:role:`text``, and explicit-title roles `:role:`Title <target>`` become `text` / `Title`; a leading `~` shows only the last component, as Sphinx renders it. - Directive marker lines (`.. note::`, `.. code-block:: python`) are removed, keeping the directive content. Markdown output is untouched, so rendered docs keep the markup. ## Related issue Fixes #351 ## Notes - New tests mirror the #306 tests: plain help strips the markup, markdown keeps it. - `test_command_help_text_strip_sphinx_markup` and `test_command_help_text_sphinx_markup_markdown` pass locally; the remaining failures in `tests/unit/test_help.py` are pre-existing in this environment (emitter-not-initiated errors, identical on the clean tree). - Canonical CLA already signed (Individual).
