## Overview

This is a React course-catalog and course-management app backed by a local JSON API. Users browse courses, open a course or create one, edit its fields, and save; course actions fetch or persist data before dispatching updates to the Flux store, which notifies subscribed views. The mock API validates course creation and generates slugs before its JSON Server router accesses the database. The listing page and several supporting modules are represented from the tree; their internals were not sampled, so uncertain links are omitted.
