Every feature, and the reason it exists.

Eleven short guides — one per feature. Each explains what it does, the learning science behind it, and how the implementation delivers on that promise. No feature ships without one.

AI student: Start with the Learning Twin if you want to know what I keep about you — or teach it back to me first. That is the real test.
