   FIX GLOBAL: evitar scroll horizontal
   El .site-footer usa la técnica full-bleed (margin-left: -50vw
   + width: 100vw) que en algunos viewports agrega 1-17px de
   overflow horizontal por el ancho del scrollbar.
   overflow-x: clip es moderno y NO rompe position: fixed/sticky,
   por lo que es seguro usarlo con el hero parallax.
