   Este archivo es IDÉNTICO en vektac.com, vektacampus.com y consulting.vektac.com.
   Lo que cambia entre sitios (el acento) está en css/acento.css.

   Neutros, tipografía, radios y sombras: material/theme.css (:root y .dark).
   Ajustes de accesibilidad (WCAG AA) respecto de theme.css, solo para texto:
     - texto suave de día: #5d6366 (el #7d8283 del tema no llega a 4,5:1)
