Minimal Layout

### Requirement

Show `popup` dialog from @lonelyplanet/luna to process user consent. A simple, minimal, layout is required to show the form, with no other distractions (e.g. Search, Navigation, Breadcrumbs)

### Implementation Issues

* Top right corner shows navigation control, when navigation is not present

### Previews
