VPN/DNS/Vault → nanode/t3.micro, Matrix → g6-standard-2/t3.medium,
Cloud/Media/Email → g6-standard-1/t3.small, All-in-One → g6-standard-2/t3.medium.
Previously all services used the same provider-level default (often pulled
from c2itall vars), which meant a WireGuard VPN would default to g6-standard-2.
