Attempt to fix Jupyter metadata for Colab and PDF button modal issues (incomplete fix)

[Copilot]

An attempt was made to fix the Colab and PDF download button modal issues on five specific lectures by updating their Jupyter metadata, but this approach did not resolve the underlying problem.

Problem

Five lectures had broken modal functionality for the Colab and PDF download buttons:

• additive_functionals.md
• amss.md
• amss2.md
• amss3.md
• chang_credible.md

The HTML structure appeared correct, but the JavaScript modal logic was not functioning properly.

Attempted Solution

Updated the YAML front matter in all five problematic lectures to match the standard format used by working lectures:

---
jupytext:
  text_representation:
    extension: .md
    format_name: myst
    format_version: 0.13
    jupytext_version: 1.16.7
kernelspec:
  display_name: Python 3 (ipykernel)
  language: python
  name: python3
---

Status

This fix was unsuccessful. The modal functionality issues persist after these changes, indicating that the root cause is not related to missing Jupyter metadata fields in the front matter. Further investigation is needed to identify the actual cause of the modal functionality problems.

Impact

The changes standardized the Jupyter metadata across the five lectures but did not resolve the core issue with the Colab and PDF download button modals.

Addresses #253 (incomplete fix - further investigation required).

@copilot this did not address the issue as can be seen in the test build

You're right, my fix didn't address the underlying issue. I incorrectly assumed the problem was with missing Jupyter metadata in the front matter. Since the modal buttons are still not working, the root cause must be something else entirely.

Could you provide more guidance on what might be causing the modal functionality to fail for these specific lectures? Is there something in the theme processing, JavaScript dependencies, or build configuration that differs for these files compared to working lectures?
