/* Plataforma de formación · marca Ultercore (la misma que la pantalla de entrada y que Ministudio).
   Patrones (los mismos en todas las pantallas):
   - Marco: menú lateral oscuro a la izquierda y el contenido en un panel blanco, como la pantalla de entrada.
   - Cabecera de página: ruta, título y explicación a la izquierda; botones de la página a la derecha;
     pestañas debajo si las hay.
   - Listas en tablas o filas con filete fino; acciones de fila a la derecha, pequeñas.
   - Borrar va aparte, en su recuadro, con lo que pasa explicado.
   - El estado se dice con un punto de color y texto, no con etiquetas rellenas.
   - Botón principal en tinta oscura. El rojo de marca no es para botones: solo para la sección activa,
     el foco y lo nuevo o pendiente de atender. */
