 * The pages, rendered on the server: the first paint is the whole vault —
3 
 * your notes on the left, the note in the middle, what it links to and
4 
 * what links back on the right — and `static/app.js` makes it an editor
5 
 * afterwards (autosave, live preview, the quick switcher, the keys).
6 
 * Without JavaScript every page still reads, and the editor still saves.
