# Build + push the dockerized pieces to the Gitea container registry:
#   punktfunk-web      — management console (web/Dockerfile, repo-root context)
#   punktfunk-docs     — documentation site (docs-site/Dockerfile)
#   punktfunk-rust-ci  — Rust CI builder image consumed by ci.yml
#   punktfunk-rust-ci-arm64cross — the above + an arm64 sysroot, for the aarch64 client legs
#   punktfunk-fedora-rpm — Fedora 43 builder image consumed by rpm.yml (Bazzite RPM)
# Host and clients are intentionally NOT containerized (see CLAUDE.md "What's left").
#
# REGISTRY_TOKEN: repo Actions secret, a PAT with write:package scope.
#
# Bootstrap note: ci.yml's rust job pulls punktfunk-rust-ci:latest from the registry, so
# this workflow (or a manual push) must have succeeded once before that job can run; on
# the same push, ci.yml builds against the PREVIOUS image. All three were seeded manually
# on 2026-06-12.
