🛰️ Orbit Observatory (3D): From a Ring Track to Kepler Ellipses

3D orbit observatory built with Blender and Three.js: an inverse-square central force integrated with RK4, circles and ellipses from the launch speed, equal-area wedges for Kepler II, the period law and vis-viva, with five numerical checks and the same physics module as the 2D version.
