 * El fondo de la imagen se maneja 100% en CSS — NO hay <img> en el HTML.
 * Así evitamos el efecto "imagen sobre imagen" que ocurría porque
 * hero_bg.jpg es en realidad una screenshot del portal anterior con texto.
 *
 * La imagen real en el VPS (/assets/img/hero_bg.jpg) ya tiene la foto
 * de estudiantes. Si la imagen del VPS fuera un screenshot, el degradado
 * fuerte del lado izquierdo la oculta completamente donde está el texto.
