Try-this now fills its space: each of up to 3 substitutions renders as a
row with a left identity block (chord chip -> modal, category tag, why)
and a right "ways to play it" block that follows the global instrument —
guitar shows up to 3 genuinely different grips (getGuitarVoicings), piano
one MiniPiano, bass a root caption. A FIXED 3-slot frame reserves height
for all three rows (present -> SubRow, absent -> dashed EmptySlot) so
suggestions #1/#2 never shift when a chord yields 2 vs 3 subs (the
anti-jump ask). Honest: add9's 2-shape roots show 2 grips, not padded
fakes. Pure parseChordName/subsForChord/pickSubject preserved (per-chord
reactivity intact). Design tokens only. Verified: build + validate-KB +
smoke 903/903 green.

Try this now shows all of the current chord's valid substitutions at
once (no more rotation), each as a card with the chord name, a mini
diagram of how to play it in the selected instrument (guitar
ChordDiagram 4-across, piano MiniPiano keyboards in a 2x2, bass a root
caption), and the plain why. Still follows the live playhead so the
set refreshes per chord as the progression evolves; honest-empty
without a key/loop; the rolled-jam visibility fallback preserved.
App.jsx change is the single instrument prop, contract-clean. Critic
PASS (combined gate: diagrams resolve, root badge correct, reactivity
verified).

The rotating Try-this card was gated on a live-detected currentChord,
so a rolled Jam Roulette (which locks a key + loop but leaves the
history empty until you play) showed nothing. TryThis now falls back
to the first loop chord that yields a substitution, so the card is
visible whenever a loop is on screen in a locked key; the live-playing
path is unchanged and honest-empty (no key / no loop) is preserved.
Critic PASS (combined gate: renders for the rolled-jam case, no
infinite render).

A compact TryThis card follows the playhead chord and shows ONE
suggestion at a time, cycling to the next valid substitution each time
the loop completes a pass (playhead wraps to a lower station). Over
Am-C-F the F cycles Dm -> Fm -> Fmaj7 -> E7 across passes, so the app
keeps offering a new idea and eventually teaches every honest move,
never a wrong one. Chip taps into ChordDetailModal; 0 subs -> no card,
1 sub -> static. Mounted App.jsx-only above RelatedProgressions in the
related slot; audio contract grep-clean; rotation logic exported pure
and StrictMode-safe. Critic PASS (2-pass rotation trace verified).
