In-line math (e.g. `$k_{limit}$`) renders without issue in the `.ipynb` files, but does not in the rendered Jupyter Book. **Does not fix:** Updating all packages did not resolve the issue. **Potential fix:** Can use alternative in-line math, for example: ``` {math}`k_{limit}` ``` This renders without issue in the Jupyter Book - *but* the **downside** is that it will not render if just viewing the `.ipynb` files.
