~to apply/merge utilities ->
comments (single and multiline)
styles (the generated CSS rules) are sorted predictably and stable — no matter in which order the rules are injected
shortcutis a way to group a known design — I develop a component with utilities and then extract it into a shortcut. In that case, I want the order to be as they were when I designed it with utilities.
applyis re-using utilities, but apply them in the order you have declared them.
