Is there an existing issue for this?

• [X] I have searched the existing issues

Describe the problem

Provide example of adaptive content layouts e.g. list-detail layout on wider screens.

Describe the solution

This would be along the lines of what's described for example in https://developer.android.com/jetpack/compose/layouts/adaptive. I realise JetNews has example of this right now but would be useful in this app to show how this might be achieved given approach used for navigation in this project.
