ARCADE BENCHMARK 10: Last Light. Build a complete playable browser arcade game as one self-contained index.html using Three.js. Defend a central beacon from approaching enemies by aiming a light beam. Light repels threats but consumes energy; collecting energy and prioritizing several approach directions must form the central tension. Escalate with varied enemy behaviours and offer a costly emergency overcharge or equivalent recovery tool. Include keyboard and touch-friendly controls, score, survival time, 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
