Hear a mastered preview, shape the premaster, then unlock the final print.
Set the target, load the source, review QC, and make cleanup moves before print. Every new customer hears a 30-second mastered preview first, then unlocks the full return after payment or active access.
Move from upload to preview to final return on one clear rail. The active step stays lit so the next action is always obvious.
