Asynchronous PDF Reporting Pipeline

.NET worker services on AWS that turn inspection data and high-resolution imagery into large PDF reports without blocking the web app. The ASP.NET Core API queues a job in SQS, an ECS Fargate worker renders the PDF and stores it in S3, and the user gets an email when it is ready. A scheduled Lambda and SQS-driven jobs archive and clean up binary assets according to retention rules.
