Pop piano: 5 progressions x 2 plays (182 total) — triads/inversions
only, one sourced add9 shimmer; ballad rolls vs voice-led pillars,
doo-wop triplets vs one-finger walks, Pachelbel inversion stair,
tonic-drone pads, octave drive. Shapes: dim7/half_dim/aug/maj6/min6
each reach >=3 placeable grips, add9 gains a movable A-shape; dim
honestly left at 2. Audit also surfaced two WRONG pre-existing shapes
(half_dim E-Barre spells {0,3,6,7}; "Open Dadd9" is Dsus2) -> backlog.
Critic PASS (~110 independent checks; all additions pc-spelled in two
keys; strictly additive diff).
