     * Configures state-based variant prefixes.

     * You can provide:
     * - An array of prefixes to use their built-in states
     * - An object mapping each prefix to an array or map of custom states
     * - A function that receives the built-in prefix map and returns such an object
     *
     * Defaults to the `ui` prefix with its built-in states only.
     *
     * @example
     * prefixes: ['ui'] // → `ui-checked:*`, `ui-open:*` using default states
     *
     * @example
     * prefixes: {

     *   aria: { expanded: 'expanded', pressed: 'pressed' },
