Documents are .md files on disk. Images are regular files. Exports to standalone HTML with Tufte CSS baked in — my use case is writing essays and uploading them directly to my personal site.

Zero dependencies, no npm install, no accounts, no build step. Just `node server.js`. ~7 files total.

Full disclosure in the README: I'm a researcher, not a JS developer, and the code was AI-generated. Contributions and code review welcome.
