| Public HTTP(S) | Internet -> Radagon -> Marika -> Morgott:Caddy  |
| Internal DNS   | Marika serves `.lan` names                      |
| Stack data     | Hosts mount Miquella at `/mnt/nas`              |
| Metrics        | otelcollector -> VictoriaMetrics -> Grafana     |
| CI deploys     | Gitea runner -> step-ca SSH cert -> target host |

All `*.alexandru.macocian.me` public traffic terminates at Caddy on Morgott.
