Jant on SG, as a field note

This site now runs as a small production Jant instance on SG: Docker Compose, dedicated Postgres, Nginx, Let's Encrypt TLS, GitHub Sync, API publishing from Minis, local backups, restore rehearsal, and Uptime Kuma checks.

The goal was not merely to get a page online. It was to make a quiet public surface that can survive routine operations: backups can be restored, health checks are watched, the repo mirrors content, and the publishing path works from an iPhone.

Small systems deserve adult supervision too.
