Build briefs

Build something you can explain, test, and hand to someone else.

Each Level Project connects to the lesson where it unlocks and includes the starter work, rubric, tests, and validation steps you need to complete it.

Do not treat setup as assumed knowledge. Level 0 has a browser-first Core project path, and the Project Workbench teaches the local workflow before later projects depend on it.
