# Unlike Atlas, this stage is deliberately NOT pinned to $BUILDPLATFORM:
# better-sqlite3 is a native module, so node_modules is architecture-specific
# and must be installed for the *target* platform. Cross-building linux/amd64
# from an arm64 Mac therefore runs this image under QEMU emulation -- see
# build.sh.

WORKDIR /app

# One apt layer for both the runtime JRE (needed by lib/circe.jar) and the
# node-gyp toolchain. python3/make/g++ are only a fallback for when
# better-sqlite3 has no prebuilt binary for the target platform; they are
# purged again so they never ship in the image. Kept as a single RUN because
# an extra `apt-get update` is disproportionately slow under emulation.
