.cargo/config.toml + aarch64-pkg-config wrapper are load-bearing for the
cross build (CI artifact job + local build-cross.sh both depend on them);
were gitignored before. souveraine.service is the systemd user unit the
packaging/deploy scripts template.
Both were stranded untracked in the Pixel3Arch tree; they source from
this repo, so they live here. deploy-phone.sh ships the cross-built
binary + user unit (seed-id excluded, machine binding stays doctrine);
PKGBUILD builds from a synced local checkout, no network fetch.
