/* ============================================================
   site.css — unica hoja de estilos del sitio. Todo con propiedades
   logicas (margin-inline-*, padding-inline-*, border-inline-*,
   text-align:start/end, float:inline-start...) en vez de left/right,
   para que el MISMO CSS sirva correcto en ar (dir="rtl") sin una
   segunda hoja espejada (BIBLIA sec. 13).

   Paleta: la unica referencia de marca real en el repo es
   logo/marca.html (verde #11C15B, oro degradado para "VIVA", onix
   #1B1B19 / platino #F4F4F2, gris #8C8F94) — se reutiliza tal cual,
   ignorando el eslogan de FACTURATica de ese fichero (no aplica a
   este producto).
