# Built with Podman/Buildah, not Docker, from the committed tree
# (`git archive HEAD`) and tagged with that commit, so a deploy ships exactly
# what git knows about. deploy.sh pushes first and refuses a dirty tree.

# The deploy host (emily) is aarch64, so that is the default target: the image
# is built for the machine it runs on, not the one running make. Podman carries
# no built-in QEMU (unlike docker buildx), so a foreign platform needs binfmt
# handlers on this host — qemu-user-binfmt is installed here. Override with e.g.
# `make build-production PLATFORM=linux/amd64`.
