Common bug when adding logging to existing Python code: calling logger.info() without importing logging module.

Error: NameError: name 'logger' is not defined

Fix:
import logging

logger = logging.getLogger(__name__)

Always add both lines at top of module when adding logging.

In discord bot config.py, save() and add_project() methods called logger.info() but module lacked import. Added imports, committed, restarted service.
