#
# Lightweight sandbox baseline — the docker-buildable form of install.sh.
#
# The sbx snapshot itself is built by template/build.sh (which runs the same
# install.sh inside a sandbox and `sbx template save`s the result). This
# Dockerfile exists so the recipe can be BUILT AND MEASURED anywhere docker
# runs, including CI and machines where sbx cannot start:
#
#   docker build -f template/Dockerfile -t sbx-lite .
#   docker images sbx-lite --format '{{.Size}}'
#
# It is also a perfectly good sandbox image on its own for the docker backend of
# the sandbox extension (SBX_BACKEND=docker).
#
# Ubuntu, because an sbx sandbox is always Ubuntu; using anything else here
# would make the measured size unrepresentative of the real template.
