/**
 * Canonical transform value shared by the composable transform utilities.
 *
 * The transform variables are layered into one declaration:
 *     transform: translate3d(var(--tw-tx), var(--tw-ty), var(--tw-tz))
 *                rotateX(var(--tw-rx)) rotateY(var(--tw-ry)) rotateZ(var(--tw-rz))
 *                skewX(var(--tw-skx)) skewY(var(--tw-sky))
 *                scale(var(--tw-sx), var(--tw-sy));
 *
 * Function order is behavioral. In particular, `skewX` must precede `skewY`
 * to match Tailwind CSS v3 composition semantics.
