- * This file is divided into 2 sections:
- *   1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
- *   2. Application imports. Files imported after ZoneJS that should be loaded before your main
- *      file.

- * The current setup is for so-called "evergreen" browsers; the last versions of browsers that

- * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
