Procedural 3D creature generator in Three.js (one-shot build)

Build with Three.js and explore a new procedurally generated 3D character style: ragdoll-like characters composed of primitive shapes that look like one seamless body via a custom, mobile-performant tech-art/shader solution, with toon styling, plus a procedural animation system that works for 2-legged, any-legged, no-legged (hopping) and flying characters with arms. Goal: a unique, easily AI-generatable style with heavy juice and polish - "HOLY SH** THIS WAS DONE WITH AI?" quality - "for the next billion dollar game." Target features: - Ragdoll-like characters made from primitive shapes that merge into one seamless body - Custom vertex shader + SDF tech that removes all seams and blends normals/colors perfectly - Fully procedural animation system that works for 2 legs, 4 legs, 6 legs, hopping, or flying - Physics-based tails/ears that stay seamlessly fused - Entire character defined in ~15 lines of JSON (so an AI can generate infinite new ones)
