🌀 Coriolis on a Turntable: Rotating vs Inertial Frame and the Inertial Circle Lab — 2D Two-Frame Map and Velocity Plane

2D companion of the Coriolis turntable lab: the room frame and the disc frame side by side with Coriolis and centrifugal acceleration arrows, a velocity-plane (hodograph) plot, radius and speed against time, and a deflection-against-spin experiment. Uses the same physics module as the 3D version.
