Local deployment (nyx server) — beta channel (tracks main = production state by default)

Managed by Nyx; deploy script: ~/deploy/smt-beta.sh [branch] (fetch, build, docker rebuild, restart; default branch: main)
Container: smt-beta (nginx:alpine, 127.0.0.1:8081 and tailnet IP 100.64.0.4:8081), image smt-beta-image
Tailnet URLs:
- http://nyx-rg3jpx6w.internal.0jm.de/ (tailscale serve → 8081; needs MagicDNS; Chrome history may autocomplete a broken https:// variant — delete it from history)
- http://100.64.0.4:8081/ (preferred: Chrome never HTTPS-upgrades IP:port URLs, no MagicDNS needed)
Note: tailscale serve --https not available on this tailnet (feature not enabled); plain HTTP inside tailnet only
