The steady hand on the bellows
In the Norse myths, Loki bet his head that the dwarf Eitri could not forge three gifts finer than the treasures the gods already had. Eitri worked the metal. His brother Brokkr worked the bellows, and the rule was simple: the bellows must not stop, or the work is ruined.
Loki turned into a fly and bit him: on the hand, then on the neck, then on the eyelid. Brokkr kept the fire even. Out came Gullinbursti, a golden boar for Freyr; Draupnir, a ring for Odin that drops eight rings of equal weight every ninth night; and Mjölnir, Thor's hammer.
At the last bite, blood in his eyes, Brokkr let go for a moment. The hammer's handle came out short. The gods still judged it the best of all the gifts.
That is the job of a design system. It is not the hammer. It is the steady hand on the bellows that keeps every piece consistent while the interruptions keep coming: a deadline, a new client, one more dashboard.
