- 3D scene: Threlte/Three.js with starfield, orbit lines, planet meshes,
sun glow, OrbitControls (orbit/zoom/pan), point lighting
- 2D velocity tails: gradient lines showing planet velocity direction/magnitude
- New WASM API: get_body_velocities_at_epoch(), get_orbit_points()
- Orbit ellipses computed in Rust, rendered in both 2D and 3D views
- Ecliptic-to-Three.js coordinate mapping (Y-up convention)
- View toggle now switches between working 2D and 3D renderers
