Knowledge Center behaviour while a jam plays, zero clicks: the station
under the playhead auto-expands to the full D-30 voicing gallery and
advances with the music; level-filtered licks strip below with
context-first sort; pin gesture inherits onFocusChord semantics;
auto-follow never emits focus or auto-plays audio. Honest space math
(piano rail scrolls as normal state), 5-commit migration order for
L-33, four rejected alternatives. Critic returned once (piano gallery
width understated ~45%), fixed, PASS on scoped re-gate.
