What an ecosystem is
An ecosystem is a boundary around a set of data, and the hub keeps every ecosystem's data apart from every other's. Everything you make in the hub belongs to one. Your workspace has an ecosystem of its own, which holds the workspace's own machinery, and every product you create gets a new ecosystem under it.
An owner stands behind each one. The owner can be a person, an organization, a persona, a container or a product. Every ecosystem also has a place in a tree of addresses. The tree starts at the hub itself: the organization that runs the platform, then its namespace, then the hub's own ecosystem, which is the first one of all. A product's address is made of its parent's address and its own slug, and two products under the same parent cannot share a slug.
A product is one of a website, a native app or a service.
