CLASSIC ARCADE BENCHMARK 06: Neon Range. Build a complete playable browser arcade game as one self-contained index.html using Three.js. Create an original light-gun-gallery-inspired precision score attack using a reticle or equivalent, with complete pointer, keyboard, and touch play. The player aims, fires, scores, misses, sees score/local high score, reaches a run end, and restarts instantly. Include at least four readable target roles: standard score target, protected no-shoot target, high-value weak-point or short-exposure target, and a target that changes the active pattern. Reward disciplined accurate target selection rather than firing at every silhouette. Add a precision chain or heat system and a limited focus action such as slow time, penetrative shot, reveal, or emergency cancel. Escalate through target relationships and priority choices, not only target count. Target identity must be clear beyond colour. Theme, setting, target appearance, camera, palette, story, and audio are open. No external asset pack. Submit final index.html only, not a mockup or explanation, with no build step.
