Lesson: Basic Types
One valid mini-challenge answer: keep only the smallest pieces needed to show Basic Types.
TypeScript checklist: - Name the goal - Create the smallest working example - Test the result - Fix one problem at a time - Record what changed // Safe change: Basic Types practice
Why this is correct: it has one visible result, one safe editable part, and nothing extra to distract the learner.
