- "Explore 3D" button on every response card — opens interactive Three.js viewer - Orbit controls (drag to rotate, scroll to zoom, auto-rotate) - 8 procedural GLB scene types: spiral galaxy, toroidal structure, crystal cavern, orbital rings, DNA helix, floating islands, wormhole, lattice world - Blender exports scenes as GLB in ~1s, cached to disk - Three.js with ACES filmic tone mapping, fog, 4-point cinematic lighting - Auto-cleanup: stops rendering when card removed from DOM - TripoSR pipeline fix: direct ComfyUI call (no self-deadlock) - AI→3D Sculpt button renamed with clear pipeline labels Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
