motion-render

Use when turning a locked brief and beat map into a film file — deterministic seek(t) scene split into classic scripts (springs, springSum, stagger, density validator, actor, CSS 3D, cursor interaction, pinned lit three.js), zero-dependency Chrome capture, staged render (stills one per beat → draft → master with subframe motion blur, stills by default), ffmpeg mp4 + GIF, VHS terminal films, audio on a measured beat grid, and verification of the delivered file.
