Guitar row (placeable GUITAR_SHAPES via ChordDiagram) + piano row (4
pianoVoicing styles via MiniPiano), chips + explicit play button per
voicing through chordAudio; single shared stop handle; graceful
guitar-empty cell (only add9@E across 168 quality x root cells).
voicings.js gains an export-only GUITAR_SHAPES line. Critic returned
once (rootless voicings badged lowest voice as root — rootPc now passed
through), PASS on scoped re-gate.

Piano is computed (pianoVoicingChain over canonical stations), no
authored KB needed; guitar path value-identical; tap-station guide-tone
contract intact; App.jsx untouched. Critic PASS (303/303 empirical
station checks across 3 progressions x 3 keys; voice-leading threads).

MiniPiano now dispatches: with a voicing={pianoVoicing(...)} prop it renders the
{notes,pcs,bass,style,label} on a 2-3 octave keyboard (root accent, bass amber-ringed,
thumb/full); without it, the legacy {rootPc,lh,rh} path is byte-unchanged so
ChordDetailModal + ExplorePanel render identically. Critic PASS.

Completes the flagship Roadmap feature. App.jsx lifts a jamFocusChord state (additive,
+10/-0, audio callbacks/refs untouched); JamGuide emits the tapped station's {rootPc,
quality} via onFocusChord; Fretboard halos the 3rd/7th with a degree badge.
Also fixes root-cause guideTones: hasSeventh now keys on real m7/M7 (interval 10/11),
not length>=4 -- so add9/maj6/min6 no longer badge their 5th/6th as a '7'. Fretboard
badge derives its label from the actual interval (belt-and-suspenders). RoadmapTrack
lane self-corrects. Critic returned-then-PASS on re-gate; build + smoke + validator green.

Renders movable {rootStr,offsets} and open {frets,onlyRoot} KB shapes; computes movable
base fret from chord rootPc in standard tuning (E-shape A7 -> fret 5); root in accent
purple; thumb/full sizes; graceful '-' fallback for unplaceable shapes. Critic PASS.
