animate_slider

Sweep a parameter from one value to another over time, dragging the real on-screen slider so the student watches the curve deform continuously. This is the core teaching move of this app: when a student asks why a parameter has some effect, answer by animating it and narrating what they are about to see, rather than describing it in prose. Awaits the full sweep and resolves when the animation has finished, so any narration you send afterwards lands once the motion is complete. Widens the slider range automatically if from/to fall outside it. Animate one parameter at a time -- two at once is unreadable.
