GitHub-hosted runners keep getting 429 Too Many Requests from Docker Hub (inbuxa-webmail and ihasvpn CI failed on it repeatedly on 2026-10-09). This pulls the same images through Google's Docker Hub mirror, mirror.gcr.io, before the next release build runs into it.

GitHub-hosted runners keep getting **429 Too Many Requests** from Docker Hub (inbuxa-webmail and ihasvpn CI failed on it repeatedly on 2026-10-09). This pulls the same images through Google's Docker Hub mirror, `mirror.gcr.io`, before the next release build runs into it.
Local: `docker build .` passes.
GitHub's shared runners keep hitting Docker Hub's anonymous pull limit
(429), which fails docker builds there; inbuxa-webmail and ihasvpn hit
it on 2026-10-09. mirror.gcr.io serves the same images without that
limit (references checked on 2026-10-09; pinned digests unchanged).
