   Los tokens de :root cubren texto/superficies/bordes neutros;
   el resto de las reglas de esta seccion oscurece puntualmente
   fondos y colores que estaban fijos en tonos pastel claros
   (KPIs, vencimiento de certificado, inputs) para que sigan
   siendo legibles sobre fondo oscuro sin perder su identidad.
   Los colores de marca/acento (--accent, --ok, --bad) y los
   badges/tags/alertas (fondo+texto pastel autocontenidos) se
   dejan igual: ya tienen buen contraste en ambos temas.
