   PANEL DE EXPERTOS
   Archivo: expertos_panel.css

   Objetivo de esta versión:
   - Mantener las tarjetas elegantes tipo glass / iPhone.
   - Mostrar una descripción recortada inicialmente para que
     todas las tarjetas se vean ordenadas.
   - Agregar un botón circular en la esquina inferior derecha.
   - Al pasar el mouse sobre el botón, cambia a un azul sutil.
   - Al dar clic, la tarjeta se expande y muestra toda la descripción.
   - Justificar el texto de las descripciones.
