⏳ Worldline Stability near a Black Hole: 2D Orbit and Spacetime Diagram

Interactive 2D view of a worldline perturbed near a Schwarzschild black hole: an orbit seen from above beside a spacetime diagram, the effective-potential well and r(tau), comparing the perturbed timeline with the unperturbed circular orbit to show where it stays stable (beyond 6M) and where it runs away or is captured.
