Add a marked extension that tokenizes math delimiters and renders them with KaTeX: `$$ ... $$` / `\[ ... \]` as block, `$ ... $` / `\( ... \)` and mid-paragraph `$$ ... $$` as inline. Inline `$ ... $` requires a non-space after the opening `$`, no newline inside, and a non-digit after the closing `$`, so prose like "$100 から $200" is left alone; `\$` still escapes a literal dollar sign. Parse errors fall back to KaTeX's red inline message instead of throwing, and math whose closing delimiter has not streamed in yet stays plain text. DOMPurify strips `semantics` and `annotation` by default, which would leak the raw TeX out of KaTeX's MathML output, so both are allowed explicitly.
