   · Siempre flotantes — nunca full-screen en ningún breakpoint
   · Backdrop con blur suave para dar profundidad sin abrumar
   · Animación de escala+opacidad en desktop, deslizamiento sutil en móvil
   · Header sticky con borde dorado de acento UABC
   · Scroll interno limpio con fade-out gradiente inferior
   · Focus trap, aria-modal, Escape para cerrar
   ·
   · z-index map (de menor a mayor):

   ·   .admin-topbar          10   (topbar dentro del flujo normal del admin)
