Add to home screen (A2HS)

The ability for a user to "install" a website and use it as if it was a natively installed app. To enable this behaviour, a website must serve a valid Web App Manifest and load it's assets through a Service Worker.

Notes

1. A manifest could be used to list apps in the Microsoft Store, which would use Edge as a back-end.

2. Safari on iOS does not support A2HS in WebViews like Chrome and Firefox.

3. Firefox is experimenting with desktop support behind the browser.ssb.enabled flag.
