Rama main · réplica de lectura del repositorio original.

# Local development infrastructure for Confabulous.
#
# This file's only job is to back the local dev loop: Postgres, MinIO, and a
# one-shot migration runner. You run the backend (`go run`) and frontend
# (`npm run dev`) natively for hot reload — see "Local development" in README.md.
#
#   docker compose -f docker-compose.infra.yml up -d --build   # infra + migrations
#   make up                                                    # same, shorter
#
# It does NOT run the app itself. The root `docker-compose.yml` is the canonical
# self-host deploy stack (full app from the prebuilt image) — see SELF-HOSTING.md.
