# HyCanvas - DEVELOPMENT image. Runs the Go backend via air live-reload (:8005)
# and the Next.js dev server (:3000) together with hot reload, against an external
# Postgres (see docker-compose.dev.yml). The source tree is bind-mounted at run
# time; the entrypoint installs deps, builds the @hc/* packages, applies
# migrations, then starts the backend (air) and frontend (next dev) under
# concurrently. This is NOT a production image - prod is the embedded
# single-binary build in `Dockerfile`.
