# Real demos for P112 "REST vs gRPC: Which One Should You Use?". Made on the Mac with Docker Desktop.
# Two machines on their own internal Docker network (nothing leaves the Mac), from one image (lab/Dockerfile):
#   stock    Ana's stock service: the same tea stock behind REST (FastAPI, port 8000) and gRPC (port 50051)
#   laptop   Ana's order service: curl, grpcurl and small Python clients (httpx, grpcio)
# Every command shown is typed into a real interactive bash in a pty (demo_driver.py): one window on the stock
# machine, two on the laptop (one of them watches a gRPC stream).
