/* ============================================================
   THE AUTONOMIA - Estilos globales compartidos
   ------------------------------------------------------------
   Branding (variables + tipografías), header (nav) y footer.
   Tomado del <style> inline de index.html para reutilizarlo en
   páginas secundarias (p. ej. politica-de-privacidad.html).
   Tema oscuro. Acento único: azul cibernético #1FB6E6.

   NOTA: index.html aún mantiene estos estilos inline; este archivo
   es la fuente compartida para las páginas nuevas. A futuro conviene
   que index.html también enlace este global.css y se elimine la
   duplicación.
