- Generate 4–8 rock groups per system with seeded placement, spacing, and slow tumble/drift motion driven by data/asteroids.json
- Add AsteroidCluster entity (Phaser container) with halo, dust motes, per-rock spins, and ship keep-out collision reusing Planet.resolve
- Integrate clusters into GameScene: load spritesheet, constrain ship post-physics, include in click-to-fly/autopilot/discovery/compass
- Synthesise unique cluster names via NameGenerator.asteroid (syllables + field suffix)
- Add dev test suite and ?seed= param for deterministic galaxy generation
- Load `assets/images/ships-player.png` as a Phaser spritesheet via
`data/ship.json` (`texture`, `frameWidth`, `frameHeight`, `frame`)
- Add `artFacing` config; Ship applies a constant `artOffset` so heading
math is unchanged while the frame art (facing north) renders correctly
- Scale sprite as `(size * scale) / frameWidth` to preserve the 46 px world
hull size and collision radius regardless of frame dimensions
- Fall back to the built-in procedural dart when the sheet is missing or
fails to load, with a console warning in GameScene.create()
- Update ship-behavior tests to account for `artOffset` in heading checks
- Add source art (`ships-player.psd`, landed-ship reference) and a demo
video; document the new pattern in README and PROJECT_NOTES
