3. This script currently reads more like a prototype or proof of concept than maintainable code. Some key issues:

• No modular structure (e.g., classes or reusable components).
• Lacks docstrings, type hints, and consistent naming.
• Contains deeply nested logic, repeated patterns, and magic constants.
• Overall hard to read and extend.
  I suggest a refactor with clearer abstractions, documentation, and separation of concerns to improve clarity and reusability.
