Ran the bundled render_markmap.py on a sample outline: it emitted a 661 KB single HTML file with all six script blocks inlined and zero external <script src> tags, so it opens offline, and the search helper correctly filtered to a matched node plus its context. That is a clear win over a hand-written static or CDN-dependent map.
