All chill-gated; trancenwaltz byte-identical. - v17: cat choir moved to bars 70–110 (back half — was way too early); hi-hats enter at 0:22 then swell in from distant over ~18 s; front-loaded decelerando 182→120 (pow fr,0.72) — ~1/3 energy gone by 1/3, well down by half; chill bars trimmed to 133 to hold ~2:45 - v18: bunny-bow given real variability/bounce — not the whole track (rests every 3rd 8-bar phrase, skips opening), 1–3 strokes, nearest-tone voice-leading, ~16% WAY lower, ~18% wrap scale-runs, ~12% BOING (arp springs up then falls); chimes ring much longer (sine arp ≈3× dur + long decay; chill bells decay 6.5 / tail 13) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
