//
//   npm run push-images                 # builds + pushes REGISTRY/*:TAG (and :latest)
//
// Config (env or a gitignored scripts/.env.release / repo .env):
//   REGISTRY   e.g. gitea.honeyy.duckdns.org/docker   (Gitea uses a LOWERCASE owner)
//   TAG        image tag (default: latest)
// You must `docker login <registry-host>` once first. Plain-HTTP internal registries also need the
// daemon's insecure-registries list (see .env.example).
