# Multi-Version Microservice Demo — Standalone (no Kubernetes)
#
# Runs everything as plain Docker containers with Dapr sidecars.
# For the full Kubernetes experience, use the main docker-compose.yml instead.
#
# Usage:
#   docker compose -f docker-compose.standalone.yml up --build
#   docker compose -f docker-compose.standalone.yml down -v
