Extract the main article from already-rendered (post-JavaScript) HTML and return clean Markdown plus metadata and diagnostics. The server fetches nothing: html is the only source, and url (optional) is used solely to absolutize relative links. Hand it the output of document.documentElement.outerHTML from a browser/devtools capture.

Convert an arbitrary HTML fragment to Markdown WITHOUT Readability article extraction (e.g. a snippet already isolated via chrome-devtools). Same Turndown + DOMPurify path as extract. The server fetches nothing: html is the only source, and url (optional) absolutizes relative links.

Return the document outline (h1-h6 headings with stable anchor ids) of already-rendered (post-JavaScript) HTML as a cheap pre-check before full extraction. No Readability scoring, no Turndown, no sanitization — a pure heading walk. The server fetches nothing: html is the only source, and url is origin context only (never fetched).
