▸case-05 When a user opens a course player page, our app has three potential sources for determining which lesson to display: the URL query string, the Redux/Pinia store's persisted state, and the course's default first lesson.

▸case-06 In our React course player sidebar, clicking a lesson in the curriculum tree updates the address bar URL.
