Class Hub Architecture

• Purpose: map the relationship between roles, the Class Hub application layer, supporting services, stored course data, and deployment.
• Suggested site placement: courses.html, /atlas/, or source-only until the public Class Hub story is fuller
• Level: project-level
• Status: source draft
