Radicale
Radicale is the Den’s CalDAV and CardDAV server — calendar and contacts, kept minimal and standards-pure. It runs as a Docker container on the Den’s Engine (Zone 1).
It does only this one job, which is why it stands apart from file sync (Seafile) rather than being bundled into it: in the Den, calendar and contacts are their own focused service, not a feature of something larger.
