What's inside

Figure-first lecturesOne clear diagram per idea, readable start to finish. The figure carries the argument; the text stays out of its way.

Practice that adaptsEndless fresh variants, weighted toward whatever you keep getting wrong. The bank notices. It holds no grudges.

Streaks & progressA daily five and a unit-by-unit board that reports exactly where you stand. Data, not vibes.
