# SocketLab – Docker Compose helper (PowerShell)
# Usage:
#   .\run.ps1                                  # default example (01_hello_server)
#   .\run.ps1 02_echo_server_blocking          # interactive echo example
#   .\run.ps1 01_hello_server down             # stop containers
#
# Interactive examples (e.g. echo) start the server in the background and
# attach the client with a live stdin so you can type messages.
