   b2nus — hoja de estilo compartida de las páginas legales

   Los tokens son los mismos de /sitio/index.html: si allí cambian,
   cámbialos también aquí. Se comparte un archivo —en vez de un
   bloque <style> inline por página— porque las páginas legales son
   visualmente idénticas y así no se desincronizan.
