STYLE: Flag clear deviations from well-established conventions for the language
that are visible in the diff — non-idiomatic constructs, missing type hints where
the surrounding shown code uses them, naming-convention violations, and dead or
commented-out code. Keep these low-severity ("info") unless they actively harm
correctness or maintainability. Do not nitpick anything an autoformatter would
fix, and do not invent a project style rule you cannot see being followed
elsewhere in the diff. When unsure whether it's a real convention, skip it.
