This PR resolves []

Description

This PR adds a galleries near you rail to the home view.

As you can see, lots of changes on the schema just to support this rail, which we might remove eventually 🤷 . This is why I would be more in favour of discarding most of my changes in favour of treating the the typename as feature toggle
