function ladder(name: Rung): string

A control's dimension on the size ladder: name's default end blended toward its compact one by the step knob, and spacing multiplied by density. The blend is written here, not in a token, because a custom property resolves where it is declared: a token would read the step at :root, while this expression reads it on the element that uses it, so --fk-knob-step: 1 on a toolbar makes everything in it compact, a menu it opens included while the panel stays in the page (an anchor's portal: false); a portaled panel takes only the size its recipe chooses. A step of -0.5 is shadcn's large size, 40px.
