When a system hides every edge, it can hide every choice as well.
A visible seam gives people a place to pause, question and repair. The best digital tools show enough of their structure to remain accountable.
Leave the join visible
A seamless experience asks us to forget how a service is assembled. That can feel effortless until a decision must be appealed or a broken step must be explained to somebody else.
A visible seam is not poor craft. It can be an honest handhold: a clear status, a reversible choice, a name for the person responsible and a way to leave without losing your work.
