/* B1 (sticky) — fix estructural.
   El header está dentro de un section de Elementor que mide lo mismo que el header
   (~97px). Cuando el header tiene position: sticky, su "containing block" es ese
   section y el rango efectivo del sticky es 0 (97 - 97 = 0). Resultado: al hacer
   scroll, el header sale del viewport junto con el section.

   Solución: hacemos sticky el SECTION que contiene el header, no el header mismo.
   El section tiene como containing block al .elementor div (1112px en /blog/),
   dando un rango de stick de ~1015px que cubre toda la página.

   El selector :has() está soportado en navegadores evergreen (Chrome 105+, Safari
   15.4+, Firefox 121+). El blog usa estas versiones en 2026.  */
