• [nitpick] The triple-quoted f-string with nested braces and manual escaping can be fragile and hard to read. Consider using textwrap.dedent to clean up indentation and externalize nested dicts or format them programmatically to avoid double-brace escaping.

• Ensure that logger is imported and initialized (e.g., via import logging and logger = logging.getLogger(__name__)) before calling logger.info, otherwise this will raise a NameError.

        logger.info("Runner started successfully and is waiting for work from the API...")
