Multiple instances coexist by giving each its own mode, directory, unit and port. Files an instance needs served at its root (a favicon, say) go in `.local/<mode>/static/` (gitignored): when that folder exists, the build ships it instead of the shared `static/`. On the host you need:
- Node 22 or newer (the relay client uses the built-in `WebSocket`).
- The unit from [`deploy/production-example.service`](deploy/production-example.service), with `ORIGIN` set to the public URL — it feeds canonical links, `robots.txt` and the sitemap.
