rafaelbergo/SistemasDistribuidos3 ? reverse-engineered prompt

Build me a small distributed shopping system with several separate services that work together.

I want a main app that lets a user place an order, and then have different services handle stock, payment, promotions, and delivery in the background. Make it feel like a real microservices demo, with each part able to run separately but also work together from one setup. If it helps, use the existing start and stop scripts and the compose file so I can bring everything up easily on my machine.

Please include a simple way to see the flow from order to payment to stock update and delivery status, and make sure the services talk to each other in a clean way. If you need current docs or examples for anything, look them up online. I mostly want this to be easy to run, easy to understand, and good for showing how distributed systems work.
