[pip-tools](https://github.com/jazzband/pip-tools) helps making builds
deterministic, controlling deps (and indirect deps) upgrades (and
versions consistency) avoiding unexpected (and potentially breaking)
changes.
We keep our direct deps in `requirements.in` from which we generate the
`requirements.txt` (where *all* deps are pinned). We also constrain dev
(and enterprise) deps based on base requirements.
Check how to [update
deps](https://github.com/jazzband/pip-tools?tab=readme-ov-file#updating-requirements).
