- 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

- Rust workspace with 4 crates: orbital-mechanics, mass-driver-core, mass-driver-wasm, mass-driver-backend
- Keplerian orbital mechanics engine with JPL elements for 14 bodies (Sun, 8 planets, Pluto, Ceres, Europa, Titan, Ganymede)
- Kepler equation solver and orbital position computation compiled to WASM
- SvelteKit frontend with Tailwind CSS, Canvas2D renderer showing animated solar system
- Orbit ellipses, planet dots with labels, Sun glow, grid, scale bar, pan/zoom controls
- Time controls (play/pause, 5 speed levels, date picker) driving live simulation
- 2D/3D view toggle (3D placeholder for Threlte integration)
