/* ── Barra v4 en cápsula (10-oct-2026) ──────────────────────────────────────
   Cápsula flotante translúcida que se compacta al bajar, indicador que se desliza
   bajo el producto, y un desplegable por producto que cambia de tamaño al pasar de
   uno a otro (como Stripe/Linear) con un mini clip del panel (escenas-barra/).
   Va en su propio fichero y se enlaza desde v4_barra(): las reglas viejas de .barra
   y .menu (estilo-v4.css, v4-web.css) se anulan aquí, no se tocan allí.
   Lógica: assets/js/v4-barra.js. */
