git.vpn.cusano.net is now behind REQUIRE_SIGNIN_VIEW (INCIDENT-2026-09-06),
so a fresh Pi can no longer anonymously `docker pull` the node images or
fetch install.sh. Plan (owner, option 3): on a `v*` tag, build the three
node images (edge-node, icecast, op25-client, arm64) and push them to a
PUBLIC registry; source and the private Gitea registry stay walled.
This workflow is wired but INERT — the job is gated on
`vars.NODE_PUBLIC_PUBLISH == 'true'`, which is unset. It triggers on tags
and skips. Enabling is three repo variables + two secrets, documented in the
file header; no code change. Reuses the existing Gitea buildcache refs so
op25 doesn't recompile from scratch.
Not turning it on now — still building the core.
