Everything is deterministic renderAt(t): 2,600 instanced agent clones, clipping-plane "materialize" effect, UnrealBloom computed at 1080p base so the glow keeps its spread at 4K, lyrics/HUD as DOM rasterized through an SVG foreignObject and composited per frame. H.264 + AAC muxed with mp4-muxer — 12k frames in \~3 min on an M4 Pro. Full video: [https://youtu.be/zwnuZJMCds4](https://youtu.be/zwnuZJMCds4) Code written with Claude — I directed and iterated on the shots.
