03 — Chorus checklist
=====================

Bass switches from whole notes to the full rhythm part.
Complete top line, no gaps — double it an octave up if the sound allows.
Off-beat key stabs return.
ONE new colour: counter-melody, a harmony a third up, or a second pad layer.
Final chorus only: the saved trick that takes it to 10.
Transition: last bar of each verse drops bass and melody for two beats.
