   --------------------------------------------------------------------------
   Este archivo lo carga index.html (<link rel="stylesheet" href="css/estilos.css">).

   Para cambiar los COLORES de todo el sitio, edita solo las variables de
   :root, justo abajo: cada color se usa en muchos lugares a través de su
   variable (por ejemplo var(--navy)), así que cambiarlo aquí lo cambia en
   todas partes.

   El archivo sigue el orden de la página: menú, portada, quiénes somos,
   enfoque, ventajas, servicios, clientes, contacto y pie. Al final están los
   ajustes para celular (@media).
