# Local bring-up for the ecomm network-service seed (SD-0001 PUC-10). From a clean
# checkout this:
#   1. starts the dev Postgres container and waits for it to be healthy (owns its
#      lifecycle — Docker is the one prerequisite, docs/BOOTSTRAP.md);
#   2. ensures the backend venv + deps;
#   3. runs the FastAPI backend (:8000, self-migrating an empty DB).
# Ctrl-C stops the backend; the container keeps running (stop it with
# `docker compose down`, or `docker compose down -v` to reset to empty).
# The storefront SPA was removed in the network-seed reset — there is no frontend dev
# server yet (the network admin UI is a future build).
