The canonical models, made interactive.
Each model has three sections: the theory (what the model says, who developed it, and the math), an interactive playground (move the parameters, watch the equilibrium move), and classroom notes (how to teach it well, common student traps, where the model breaks).

For teachers
Built to be taught from.
Three sections per model
Theory, playground, classroom notes — so a 50-minute lecture has the structure already in place.
Interactive, not just animated
Students change parameters; the equilibrium moves. The intuition lands faster than chalkboard derivation alone.
Honest caveats
Each model section includes where the model breaks, common student traps, and the next-step extensions in the literature.
