# GazingEngageMent — developer cheatsheet
#
# Two kinds of targets here:
#   1. App targets  (run inside the devcontainer, or natively if you have
#      python+node installed). They operate on the backend and frontend.
#   2. Container targets (run on the HOST). They wrap `docker compose` so you
#      don't need to remember the flags.
#
# Quick start (host):
#     make container-up           # build + start the devcontainer
#     make container-shell        # open a shell inside
#     # then inside the container:
#     make install
#     make dev                    # runs backend + frontend together
#
# Note: .venv and node_modules live in named Docker volumes, NOT in the
# project folder. See .devcontainer/docker-compose.yml for the volume layout.
