Every note is a markdown file with YAML frontmatter for its metadata; `[[wiki-links]]` in the body become a graph of backlinks, computed fresh on every read so they can never drift out of date. A zero-dependency Node server (nothing to `npm install`) serves a no-build single-page app for capturing, browsing, and linking notes, plus a force-directed graph view and a slide-style "Present" mode that walks the link graph.

Why it's built this way

iCloud Drive already syncs files between machines for free, so the sync layer is just "put the files in the right folder." The data stays inspectable and greppable in Finder, and survives the app itself — there's no export step, because there was never a lock-in format to escape.
