Every choice explains the system.
Color has a job.
Color identifies an actor, operation, or outcome.
Motion explains work.
Breath, orbit, transfer, and promotion carry meaning.
Structure stays quiet.
Hairlines and spacing create hierarchy before panels do.
Complexity stays inspectable.
Name every actor, threshold, and result.
