How the hosted version is constrained

The production site is served as static files with a Content Security Policy that blocks browser network requests from the app after load using connect-src 'none'. The app code and its runtime dependencies are served from this domain.

Offline use

You can also use the downloadable single-file version from the offline copy page. It runs without an internet connection after download.
