The Course pane lists the 21 lessons, shows a lesson's text and exercise,
loads its starter, and checks the program in the editor with the engine
(engine_course_check in the page, the same commands in the desktop app):
each case's verdict, each rule, What went wrong? from the diagnostics, the
verdict and the critique, the hints one at a time with the engine's pointer,
and a hint from the assistant when a model is connected, any program in its
answer held back. Progress is kept only in this browser and says so.
The interface's words are data, locales/<locale>/<area>.json for every part,
English the source and Simplified Chinese marked machine-assisted; the Studio
follows the browser's language until the reader picks one with the switch.
test/locales.test.mjs holds every locale to every key and placeholder. The
e2e checks the course in English and in Chinese. wai-web's engine tests pin
23 native and 16 wasm32, a course check the same bytes in both.
