       #2068B2 es el azul del isotipo, medido sobre el archivo del favicon,
       y el mismo que usa el portal de clientes (assets/css/portal.css).
       Antes esto era #1e40af -> #06b6d4, un azul-cian de la paleta de
       Tailwind sin relacion con la marca ni con el portal: el operador veia
       un color en el panel y el cliente otro distinto en el suyo.

       El degradado se conserva porque lo usan el boton primario, los
       enlaces activos de la barra lateral y el titulo, pero ahora recorre
       dos tonos del MISMO azul en vez de saltar de familia. */
