// #413: getNode's markdown-default format, its JSON opt-in, the non-top-level
// AUTO fallback to JSON, and comment-anchor preservation (incl. resolved) on the
// markdown read. getNode only reads (getPageRaw), so a lightweight subclass that
// stubs auth + the page fetch is enough — no collab socket needed.
