Replaced 5-line tp() call with full conductor-style arrangement: - chromRun() helper plays fast chromatic scales in background, only every 4th note is hittable (conducting the accent peaks) - 7 sections: intro → first chromatic runs → development → E minor modulation → fff recapitulation → climax → coda - Three speed tiers (0.09s, 0.065s, 0.055s per note) for increasing intensity across sections - Continuous Am harmonic bed with strings/bass - Duration expanded from ~35s to ~88s https://claude.ai/code/session_01TFVkxq4PYhkSFGYHEi4uqY
