# Story Kit – single-container runtime
# All components (server, agents, web UI) run inside this container.
# The target project repo is bind-mounted at /workspace.
#
# Build:   docker build -t storkit -f docker/Dockerfile .
# Run:     docker compose -f docker/docker-compose.yml up
#
# Tested with: OrbStack (recommended on macOS), Docker Desktop (slower bind mounts)
