### Single-source responsibility is preferred because the counterbalance, the curtain weight, the guide engagement, and the operator must be matched as a system; splitting responsibility across vendors creates a coordination gap precisely at the interface that determines whether the door is balanced and whether the operator can move the curtain without overloading. {note}
