ARCADE BENCHMARK 07: Magnet Mine. Build a complete playable browser arcade game as one self-contained index.html using Three.js. A salvage craft moves through scrap and mines using attraction and repulsion. The magnet must visibly move objects, collect valuable scrap, clear paths, and create danger because mines react too. Score salvage deliveries, disarms or narrow escapes, and clever multipliers. Escalate with denser fields and object interactions while keeping force and mine behaviour understandable. Include keyboard and touch-friendly controls, score, fail state, high-score display, and instant restart. Submit the final index.html only, not a mockup or explanation. It must run in a modern browser with no build step. Full design reference: https://gist.github.com/ponderingdemocritus/cf2b3f3933cadd06af9fe0e0c5aeabdd#file-index-html
