This update introduces a major overhaul of the course and unit-plan workflows, centralizing logic to eliminate triplicated AI fallback code and unify component usage across admin and teacher interfaces. The new shared UnitPlanWizard streamlines course creation with manual or auto-computed timelines, while upgraded detail pages and a consolidated browsing experience improve usability for both students and instructors. By abstracting the core infrastructure into shared library functions and common UI components, we've significantly reduced technical debt and ensured consistent behavior across the application.
