Prompt

    Refactor the code below for readability and structure. **Do not change its observable behavior** — the same inputs must produce the same outputs and side effects.

Code:
{{code}}

Goals (optional — e.g. reduce nesting, extract functions, clearer names, remove duplication):
{{goals}}

Please:
1. Return the refactored code.
2. Summarize what you changed and why, as a short bulleted list.
3. Flag anything you were tempted to change but left alone because it might alter behavior.

If a "cleanup" would risk changing behavior, don't make it silently — point it out and let me decide. If the code's intended behavior is unclear in places, ask before assuming.
