Dynamic latency ships as ruled; the restart cost is re-attributed to our own setActive and filed in TODO. The reflow splits canvas (W1-T4) from arrangement (W3-T1); preserve-time-stretch moves to W1-T5.
Two-row deck reflow (sound/contour), double-height MASTER with limiter and meter, PITCH/RATE deck, unit-driven knob law, contour-trace fix, and a re-approached loop/crossfade UX. Folds rulings Γ-F1..Γ-F5; opens Γ-F6.
