Python Script to Notebook Converter

Prompt

Convert this Python script into a well-structured Jupyter notebook.

Script purpose: [WHAT THIS SCRIPT DOES]
Target audience: [WHO WILL USE / READ THIS NOTEBOOK]

Rules for conversion:
1. Break the script into logical sections with **markdown header cells**
2. Add a **first cell** with: title, author, date, purpose, and required libraries
3. Add a **parameter cell** near the top with all hardcoded values pulled out as named variables
4. Add **explanatory markdown cells** before any complex code block (1-3 sentences)
5. Add **inline comments** to lines that aren't self-evident
6. Add a **final summary cell** describing what the notebook produced
7. Flag any code that should NOT be run more than once (e.g., one-time data writes) with a ⚠️ markdown warning

Here's the script:
```python
[PASTE PYTHON SCRIPT]
```

Output each cell labeled as: [MARKDOWN] or [CODE] followed by the cell content.
