/* ============================================================
   /login — mismo sistema visual que la landing, /como-funciona y /api-docs (misma paleta,
   misma tipografía, cargadas vía landing.css bajo body.landing). Esta página NO lleva el
   header ni el footer del resto del sitio — es un split de dos paneles, así que todo el
   layout y los componentes (campo, alerta, tarjeta de evidencia oscura) son nuevos, con
   prefijo lg-.

   REGLA DE SCROLL: overflow-x:clip en el body, nunca hidden — hidden convertiría a body en
   contenedor de scroll y rompería cualquier position:sticky descendiente futuro.
