    # neuere Version meldet Abweichungen an Code, den niemand angefasst hat.

    # Die Version steht an ZWEI Stellen: hier und als `rev:` in
    # .pre-commit-config.yaml. Die CI hat keinen eigenen Pin-Schritt mehr, sie
    # installiert ueber das `dev`-Extra mit. Beide Stellen im selben Commit
    # bumpen — `scripts/check_ruff_pin.py` wird rot, wenn eine zurueckbleibt.

    # Beim Anheben: beide Versionen aendern, `ruff format` einmal ueber die
    # gelinteten Pfade laufen lassen und das Ergebnis mit committen.
