Rehearsal/play session on the UMC rig (SOF->UMC migration validated end to
end tonight): electric_hammer, bombe_dj, ete_a_mauerpark, vague_de_crime,
gimme_acid, take_5_drops tuned; raph collab tracks (desire, mafia_sans_serif,
piment_bresilien) touched; backlog.md and armada calibration catalogs
regenerated alongside.

Committing as a clean checkpoint before starting the d1-d12 channel
harmonization + LCXL fader remap (task #46) and the sample/synth reference
cleanup (task #45), so those land as reviewable diffs against a known-good
base rather than mixed in with tonight's live tuning.
