/**

 *
 * Browsers ignore `@property` inside a shadow root, so a custom property the
 * sheet registers there keeps no initial value, and every declaration built
 * on it is invalid. Tailwind v4's shadow, ring, transform and gradient
 * utilities all read properties registered that way. A registration in the
 * document applies in every shadow root, so the copy makes them work.
