/* ============================================================
 * StarBorder (React Bits) — port vanilla, sin dependencias.
 * Dos haces de luz barren el borde en direcciones opuestas.
 * Uso: <button class="..." data-star data-star-color="#34d399"
 *        data-star-speed="5s" data-star-thickness="1.5">Texto</button>
 * El enhancer (star-border.js) envuelve el contenido en
 * .inner-content y setea color/velocidad/grosor. Acá solo la
 * parte visual; el botón conserva sus clases y su radio.
