// A third image workflow rather than a reuse of learning_hub, because the two

// this feature needs to keep. Filing a private illustration under learning_hub
// would make it linkable into published content by anyone who knew its id.
//
// Nothing else is needed to serve them: asset() already grants the owner, so a
// my_resources image is visible to the person who made it and to nobody else.
