Based off the initial lo-fi design concepts, this issue involves creation of a new Header/Breadcrumb component, which is quite similar to the <ActionHeader /> in Store:

Let's try to keep an accessible header structure in our app – since I don't see a better place for a "page title", we can either make the breadcrumb here an h1, or use the screen-reader-text class to add an "invisible" header (though visible and styled like a header would be best).
