I'm not sure I understand how to push the PWA theme into production.
So you have to install the PWA theme, just like a regular theme and this provides the app shell
Then you install the pwa-studio with the Venia theme, this give you a DEV server that you can code and test on
When you're ready, you build this app and push it to the PWA theme?
When you call the url www.yourmagentostore.com
The PWA theme sends the app shell?
Is this right?
