• Respond with a 200 when offline
• start_url should respond with a 200 when offline.

Installable

• Use HTTPS
• Register a service worker that controls page and start_url
• Web app manifest should meet the installability requirements

PWA Optimized

• Redirect HTTP traffic to HTTPS
• Configure for a custom splash screen
• Set a theme color for the address bar.
• Content should be sized correctly for the viewport
