Module math 

Optional math rendering hooks.

Upstream Mermaid renders $$...$$ fragments via KaTeX and measures the resulting HTML in a browser DOM. merman is headless and pure-Rust by default, so math rendering is modeled as an optional, pluggable backend.

The default implementation is a no-op. For parity work, a Node.js-backed KaTeX renderer is provided, and the ratex-math feature enables a pure-Rust RaTeX renderer for supported labels.
