 * NEXTIUSPLAYER — carcasa del reproductor de lecciones
 * Patron documentado en random/DOCUMENTACION/NEXTIUSPLAYER_CUSTOM.md

 * Todo va con el prefijo nx-: dentro del admin de Perfex, nombres como .player,
 * .bar, .poster o .time chocarian con Bootstrap 3 y con el tema.
 *
 * Los colores NO se escriben aqui: los inyecta el helper como --nx-brand y
 * --nx-fg en el style del contenedor, con lo que se configura en
 * Academia > Configuracion > Reproductor.
