Solid single-box walkthrough — MinIO + Nginx is a clean way to get an S3-shaped edge on one machine. The pain we keep hitting shows up the moment you add a second region: who owns purge, who owns TLS and site assignment, and how you avoid SSH-and-pray. We have been building an open-source CDN control plane (CDNCA, AGPL-3.0) around self-hosted nodes plus a plugin marketplace; marketplace features roll out release by release. Curious whether you kept this as one node or already split origin and edge.
