CLASSIC ARCADE BENCHMARK 03: Crane Breaker. Build a complete playable browser arcade game as one self-contained index.html using Three.js. Make an original claw-machine precision score attack. The player moves an overhead grabber across a readable prize field, commits to a drop, visibly grabs objects, carries them to a collection chute, scores, and restarts instantly after a run. Include keyboard and touch controls, score and local high score, limited drops or time, and at least four object roles: reliable low-value objects, unstable medium-value objects, rare high-value objects, and an object that changes board or machine state. Grabs must be explainable from visible alignment and contact rather than random probability. Add a pressure meter that makes greedy or failed drops raise complications, plus one limited tactical tool such as a precision grip, wide grab, stabiliser, or slow alignment. Reward planned collections and board manipulation. Theme, prizes, materials, story, and audio are open. No external asset pack. Submit final index.html only, no mockup or explanation, with no build step.
