The content of the PR is good ✅

The failing tests would need to be addressed:

I don't know how the snapshots are handled (is this documented somewhere?) but something is failing and would need to be fixed, see https://github.com/MDAnalysis/UserGuide/actions/runs/14936015006/job/41963506015?pr=426 . @lilyminium @RMeli do you know?

The formatting should be

from MDAnalysisTests.topology.test_lammpsdata import (
    LammpsBase,
    TestDumpParserFull,
)

says the pre-commit hook check.

It would be good to get this merged so that we can move any of the other PRs along.

Sorry, I was OOO. The snapshots might need to be re-generated. I don't recall where this is documented, I'll have a look.

Thank you @RMeli !!!

For a release I used the following instructions: https://userguide.mdanalysis.org/stable/preparing_releases_and_hotfixes.html#create-a-release-of-the-userguide.

The section contains instructions on how to generate the snapshots:

cd doc/source/scripts
python -m pytest tests/snapshot/ --snapshot-update

Thank you @lilyminium and @RMeli !!!
