About WebMotion

Compose video in the DOM, encode it with WebCodecs, download an MP4. No FFmpeg, no headless Chrome, no render farm. Every frame is a pure function of the frame index. The frame number is drawn by the scene, so scrubbing anywhere keeps it honest. Everything visible is a pure function of the current frame. Give the renderer a frame index and it draws exactly one image. Seeking is exact because there is no state to wind forward.
