force metaphor

A mechanical arrangement where a small input moves a large load. Lever, spring, pulley, wedge, domino. You pour a dependency or a leverage claim into it: this small thing, applied here, moves that big thing. It draws asymmetry better than any chart, because the eye reads the long arm and the short arm at once. What it adds for free is a fixed exchange rate. A lever's ratio is a property of the bar, and your ratio almost never is.

Best when the content is one small input with an outsized effect, and the location of the input is the point.
