/**
* In the Web build, we center all content so that it mirrors the
* mobile experience (a single narrow column). We then place a UI
* shell around the content if you're in desktop.
*
* Because scrolling is handled by components deep in the hierarchy,
* we can't just wrap the top-level element with a max width. The
* centering has to be done at the ScrollView.
*
* These components wrap the RN ScrollView-based components to provide
* consistent layout. It also provides <CenteredView> for views that
* need to match layout but which aren't scrolled.
