[bug\_fix] ImportError: cannot import name 'foo' from partially initialized module 'bar' \(most likely due to a circular import\)

Break the cycle by moving the import inside the function or method that uses it, or refactor shared code into a third module. For type hints, use 'from \_\_future\_\_ import annotations' and typing.TYPE\_CHECKING.

Journey Context:
You have a.py importing from b.py and b.py importing from a.py. At startup you get an ImportError about a partially initialized module. You sprinkle print\(\_\_name\_\_\) traces and see a imports b, then b imports a before a has finished executing, so the requested name does not yet exist. Moving the import into the function that needs it delays execution until both modules are fully initialized. The cleanest fix is extracting the shared interface into a separate module that neither a nor b depends on circularly.
