New npm Packages Fix LLM Math Notation Mismatch in Markdown Rendering

Large language models like OpenAI's commonly output math using TeX-style delimiters such as \(...\) and \[...\], while most Markdown math plugins only recognize dollar-sign syntax like $...$ and $$...$$. A developer attempted to resolve this mismatch using regex-based preprocessing but found it unreliable, particularly with nested code blocks, escaped characters, and unclosed delimiters in streamed model output. Instead of patching the input, the developer extended the micromark tokenizer to natively recognize both delimiter styles. This approach produced two open-source packages — micromark-extension-math-extended and remark-math-extended — which support all four math delimiter formats simultaneously. The remark-math-extended package is designed as a drop-in replacement for the existing remark-math plugin in unified/remark pipelines.
