🪐 Orbits in d Spatial Dimensions: 2D Top-Down Sandbox

Top-down sandbox showing how a central force changes with the number of spatial dimensions: the field falls as 1/r^(d-1), so orbits are closed ellipses at d=3, rosettes at d=2, and unstable at d=4. Sling bodies with the mouse, drag the source, and read the measured periapsis shift against theory.
