# ── repositories ────────────────────────────────────────────────────────
# PVE 9 / Debian 13 uses deb822 (.sources) files, NOT the old one-line .list
# format, so these use deb822_repository rather than apt_repository.
#
# NOTE the FQCN: deb822_repository has been promoted INTO ansible-core, so it is
# `ansible.builtin.deb822_repository`. It is NOT in community.general (which
# ships only apt_repo, for openSUSE) -- reaching for the community.general name
# fails with "couldn't resolve module/action".
