   Define las variables de color, la barra de navegación, el pie y el botón de
   WhatsApp para TODAS las páginas del sitio, incluidas las que no cargan
   dark-theme.css (las que siguen usando Bootstrap).

   Orden de carga esperado:
     Portada y páginas oscuras : dark-theme.css → mm-shell.css → mm-2026.css
     Páginas internas Bootstrap: bootstrap → mm-shell.css → mm-2026.css → mm-inner.css

   Los valores de :root son idénticos a los de dark-theme.css, así que cargar
   ambas hojas no produce ningún conflicto.
