Design review

Course UI, mobile-first, with the timer

This build takes the approved course redesign and makes it work on a phone, adding the course time tracker we discussed. Same visual language, one responsive layout for phone and desktop. Best viewed on your phone, but resizing this window works too.

How the timer works

It counts active time only. The clock stops when the tab is hidden or when there has been no activity for two minutes, and time spent away is never added. There is no manual pause button, so there is nothing to game.

To see that without waiting, add ?demo=1 to any page for a panel that can fast-forward the clock and trigger the pause. Try it on lesson 1.1.1.
