Subject: [PATCH] Rewrite Flight of the Bumblebee in conductor-style
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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
