Spacing
Tailwind's default 0.25rem stepping is the kit's spacing rhythm. Components reach for these utilities — never raw px.

Why
One vertical rhythm everywhere — components stack predictably. Any value you reach for that isn't in this scale is a smell; either extend the scale or reuse what's already here.
