We're using a line length of 88 characters in our code base, and that's also the standard in the Python community nowadays (e.g., enforced by Ruff and Black). Therefore, I think it would be great if code blocks on our documentation website could be rendered without horizontal scrollbars. For example, see the very last code block at the bottom of https://mne.tools/stable/auto_tutorials/epochs/40_autogenerate_metadata.html.
