-/// Vendored [marked](https://github.com/markedjs/marked) v4.0.2 UMD bundle.
-/// Exposes a global `marked` with `.parse(src, opts)` returning HTML. Used

-/// `ask` / `answer` / assistant text) with basic markdown — paragraphs,

+/// undefined and markdown silently falling back to raw text (issue #244).
