   soporte-alerta.css — Estilos para artículos de alerta técnica
   (soporte/alerta-eku-autenticacion-cliente.html y futuros)

   Prefijo `.alerta-` a propósito: `.sd-section` (soporte-detalle.css) no
   tiene hoy estilos para <p>/<h3>/<ul> sueltos y no los agrego ahí para no
   afectar otras páginas ya en producción que comparten esa clase. Todo acá
   vive scopeado bajo `.alerta-prose` o clases propias.
