🪐 3D Gravitational Particle Field

Hundreds of glowing particles orbit one or more massive stars under a genuine inverse-square gravity law (F = G·m / d²), extended from the 2D original into full 3D space with a free-orbiting camera. Drag to rotate the view, scroll to zoom, hold Shift while dragging to plant a temporary attractor, or Ctrl to repel — the same attract/repel interaction as the flat version, now with real depth.
