<supernote-viewer> demo

Standalone build of the <supernote-viewer> custom element from the supernote-obsidian-plugin project (issue #183) - runs entirely in this page, with no Obsidian involved. Pick a .note file from your Supernote device to view it.

Build the bundle first: this page loads ./supernote-viewer.js, which isn't checked into the repo - run npm run build:webcomponent from the project root, then serve this directory over http(s) (module scripts can't load from a file:// URL) - e.g. npx serve . from the project root, then open /demo/.
