 * RIZOMA MAUX · Video tutorial (js/core/video_tutorial.js)
 * -----------------------------------------------------------------------------
 * Reproductor colapsable: «grande» (modal), «mini» (flotante abajo a la derecha,
 * la aplicación sigue usable) y «barra» (solo la cabecera; la narración sigue).
 * Todas las clases llevan el prefijo vt- para no chocar con las de la app.
 * Usa los tokens de css/tokens.css (tema claro y oscuro).
