PR Summary

Medium Risk
Moderate risk because it changes post-processing of the root AST structure, which can affect document rendering/order across different MDX trees, but it’s narrowly scoped and covered by a new unit test.

Overview
Ensures generated GFM footnotes aren’t dropped or inserted into a hard-coded subtree by detecting the footnotes <section> via dataFootnotes/footnotes class, removing it from the root, and appending it to the Layout node’s children (or back to root if no Layout exists).

Adds a focused unit test asserting that the transformer moves the footnotes section under Layout rather than leaving it at the root.
