foldkit-mixins/utilities: one-idea pieces over the shipped scales, so
Utilities.p('md') is padding: var(--fk-space-md). A step is a token name
of Theme.tokens (and a color a token name of Theme.oklch), so a step the
scale lacks is a type error and the value still follows the density knob
and a theme's overrides: the theme stays the one source of truth for sizes.
Each is a rule on the element (Style.self), unlayered like the other
subpaths' pieces, so it takes the layer of the style it is composed into and
a plain declaration beside it wins per property. Compose them like any piece:
[U.flex, U.gap('sm'), { color: t.text.muted }].
