Mismo límite blando que la API (60 peticiones por minuto e IP) y misma postura de privacidad: los cuerpos de las peticiones se procesan y se descartan, nunca se guardan, y el procesado de archivos no tiene endpoint de servidor a propósito. El servidor es HTTP sin estado: nada persiste entre llamadas.
