Hi team, please review this when you have a chance. Thanks!

Thanks for picking this up and for the clear description of the issue being fixed. The problem is well understood and the approach is on the right track.

Issues Found

1. CSS specificity issue

The file already contains:

article.markdown h1 {
  margin-bottom: 1rem;
}

Since article.markdown h1 is more specific than the general h1 rule being added here, the more specific rule wins and the fix will likely not apply where the bug actually occurs. Please update the selector to article.markdown h1 to ensure the fix applies in the correct context.

2. Padding side effects

Adding padding-bottom directly to h1 can affect layouts that rely on the h1 box model for positioning. Please test across multiple doc pages to confirm no unintended layout shifts.

3. No visual evidence

Please provide a screenshot or short video showing the bug and the fix.

Please also rebase against main before resubmitting as there are merge conflicts with other open PRs touching the same file.
