-// MathJax config for Material for MkDocs + pymdownx.arithmatex (generic mode).
+// MathJax config covering both rendering paths on this site:
+//   - Markdown pages via pymdownx.arithmatex (generic): math arrives as

+//   - Jupyter notebooks via mkdocs-jupyter: math arrives as raw $...$ / $$...$$.
+// So we accept both delimiter styles and let MathJax scan the whole page (it
+// skips <pre>/<code>/<script> by default, so $ in code is untouched).
