🕳️ Singularity Infall: Orbit Plane and Effective Potential (2D)

Top-down 2D view of a test mass falling around a Schwarzschild black hole. Drag the start point and launch-velocity arrow, watch the relativistic orbit precess against a Newtonian ghost, and follow the effective-potential graph to the singularity where tidal forces diverge.
