MathLM support

Anyone has an idea how this would be possible? Not to familiar with source code my self, so blindly tinkering will get me nowhere.

No file, test, or entry point is named in the issue; first clarify what “MathLM” means and the expected supported behavior, then trace the repository’s HTML-rendering path. Done means the requested support is implemented with a demonstrable test or example, but the issue provides no concrete acceptance criteria.
