- Each plugin is a JavaScript file running in its own Web Worker, with requested capabilities and approval for changes to data it does not own.
Field notes
The homepage acts as its own demonstration: its chapters and switchboard are described as plugins, and switching sections off changes the page. The project says plugins run in separate Web Workers, declare their needs, and require approval to change data they do not own. It also says the app uses plain HTML, CSS, and JavaScript with no build step; notes and switches stay in the browser.
