The original zero-shot build — and the collection's first WebGL game. Real-time 3D via Three.js (r128, bundled locally, no CDN and no network request). Each fighter is an articulated humanoid of primitive meshes in a joint hierarchy; attacks are per-joint poses with phased startup / active / recovery windows. The fight logic runs on a fixed 60 Hz timestep decoupled from rendering: frame-data hitboxes live only during active frames, height-checked blocking, decaying knockback with juggle decay, hitstop, and special-move detection from a rolling input buffer (quarter-circle motions). A range-bucketing CPU picks weighted actions with a reaction delay; a side camera tracks the midpoint and dollies back as the fighters separate. All sound is procedural Web Audio — impact, block, whiff, jump/land, fireball, KO, round-start and victory cues, the smack of a hit scaled by its power.
