Apple-Style Kinetic Recap

# apple-motion

Every default here is measured, not guessed: six Apple recap videos (1107 s, 33,187 frames) went
through a forensic pipeline (OCR text tracking, spring fitting, optical flow, beat tracking,
loudness), and the pipeline itself was calibrated on renders with known springs and fonts.
