Can this logic be either moved into Can this logic be either moved into `<FeaturedCategory>` and/or moved into a selector that is called by `<FeaturedCategory>`?
I moved all this logic into I can kind of see doing to logic for each category separately but I would need to think about it and it doesn't seem like it will be nearly as clean as this. I moved all this logic into `selectDiscover` and am calling it from the `Discover` page and it's working correctly. Calling it from `<FeaturedCategory>` doesn't make sense to me because the selector returns an object which is mapped to many `<FeaturedCategory>`s in the view.

i dont think this would block merging, however, here is a rough sketch of how i would do this
```
