    # Three separate mypy invocations, not one over all three trees: `petbox/` is a namespace
    # package with no __init__.py, so `mypy petbox/dca tests docs` makes mypy resolve
    # petbox/dca/__init__.py as both `dca` and `petbox.dca` and abort with "Source file found
    # twice under different module names".
    #
    # --strict is pinned explicitly even though pyproject.toml sets `strict = true`, so that a
    # flag dropped from the config fails here rather than silently widening what CI accepts.
