Decision Matrix: When to Use Which Tool

FastAPI `BackgroundTasks`: Zero dependencies, runs in the same process, jobs are lost if the server restarts (best for: email receipts, audit logs).

Celery + Redis/RabbitMQ: Distributed worker nodes, retry guarantees, scheduled tasks (best for: AI model inference, video encoding, large scraping jobs).
