The shared block library behind NWIOI's course tooling. A document is an ordered list of blocks; every block kind is a plugin, so discussions, assignments and labs sit alongside slides and quizzes as first-class content.
Grace is a component, not a product you log into. Documents are provisioned by NWIOI Instruct when an instructor is invited to build a class, and delivered to students through the NWIOI LMS, where enrollment decides who can see what. If you're an instructor, your editing link arrives by email.
Faculty sign-in is coming; until then Grace has no browser-facing way to create a document, deliberately.
What every consuming app reads instead of keeping its own copy — /api/registry.
