Start it on the server. Check it from the couch.
Every host's sessions appear in one list, labelled by host and filterable. New Session asks which host. An organization on another host opens there, with its pages and its overseer.
Settings, themes, extensions and logins can be kept in step, each behind its own switch. With logins on, they're copied to every host. Two different logins for the same provider are shown as a conflict for you to settle, never overwritten.
Hosts trust each other by Tailscale identity, with no token between them. Your browser unlocks a host with its token or a one-use pairing code, and through it can use every peer. Every host in a mesh must be reachable by the same devices, and run the same Sova build. docs/mesh.md covers the setup.
