 ## Using gyb_utils.py for Shared Utilities
 
 The `gyb_utils.py` file in the Scribble GYB configuration allows you to declare global variables, helper functions, or imports that can be reused across different GYB templates. This is especially useful when you have common logic or variables that need to be shared.
