/**
 * This Node script lists all files that should be cached by the service worker,
 * so it can continue to work in offline mode. The output can be copy-pasted in the service-worker.js file.
 * These files need to be listed manually, because the service-worker.js file cannot possibly know
 * which files it should cache during runtime.
 * This is a fragile approach that will break when the app is refactored.
