name: Build base image
# Path-filtered so it fires when the base Dockerfile (or this workflow)
# changes, weekly via cron so Debian security updates land without us
# remembering to bump anything, and on-demand via workflow_dispatch.
#
# The weekly cron passes CACHE_BUST=<ISO week> as a build-arg so the
# apt layers in Dockerfile.base re-execute (otherwise BuildKit's layer
# cache would short-circuit `apt-get update` on a deterministic input
# and silently skip security patches).
