⚠️ When it works and when it doesn't

For v6: request key and progression in Style. Lyrics markup is an additional cue; check exact chords and transitions by listening.

Unreliable: jazz/extended chords, mid-song key changes, specific voicings/inversions.

Important: chords must be in square brackets — otherwise Suno sings "A minor, F, G" out loud. This is probabilistic: best shot, not a 100% guarantee.
