Review Summary

I am approving this submission. The sorted_variables dictionary is correctly defined with exactly two keys ("mutable" and "immutable") and all eight variables appear exactly once in the appropriate lists, matching Python’s mutability rules. The solution runs without dependencies and meets all core requirements.

Minor, non-blocking suggestions:

• In app/main.py, fix the spacing around the key so it reads "mutable": instead of "mutable" : (cosmetic).
• Optionally add a quick self-check, e.g., assert len(sorted_variables["mutable"]) + len(sorted_variables["immutable"]) == 8, and a brief comment describing the purpose of sorted_variables.

Nice work aligning precisely with the task—clean and correct implementation.
