Implement admin for Primary Hero Shelf (original) (raw)

Part of this PRD.

The Primary Hero Shelf in the homepage will feature one extension, chosen from a subset of Recommended extensions:

Since this will only work with Recommended extensions, it seems sensible to extend the admin we already have for it.

For the admin of a Recommended extension, add:

• Featured Image, chosen from a pool of predetermined images.
• Background color, used for the gradient.
• Featured on Primary Hero Shelf, checkbox that adds or removes the extension from the set. The checkbox shouldn't be toggled on if the other two properties haven't been set, or if the extension is only in the Recommendable state. There should always be at least one extension with the checkbox turned on.
