Play

Short browser games that turn each topic's ideas into things you operate instead of read: something breaks, you diagnose it, you fix it. They run entirely in your browser, with no server and nothing to install.

Every chaos event in a game links to the note that explains it, so a loss is a pointer to the right section. Every game is also checked in CI: its scenarios must reference real note sections, and a scripted winning run must actually win.
