### too opinionated style checks

## might be nice .. but later and I don't wanna make it strict
    "E402",  # Module level import not at top of file

### maybe consider these soon
    # sometimes it's useful to give a variable a name even if we don't use it as a documentation
    # on the other hand, often is a sign of error

###

    "RUF100",  # unused noqa -- handle later
