   MARCA SIEMPRE EN MODO CLARO
   SeptiGenesis es una marca de fondo blanco + acentos teal (igual a
   septigenesis.com). Se DESACTIVA el volteo automático a modo oscuro:
   con dark mode del navegador, los textos azul-oscuro (#143e6b) del H1
   y el logo quedaban invisibles sobre fondo oscuro. El sitio conserva
   su paleta clara sin importar la preferencia del sistema.
