"""The web dashboard proxy must follow DECNET_API_HOST.

|
Hardcoding 127.0.0.1 broke deploys where the operator binds the API to
|
|
a specific tailnet/VPN address: the API drops loopback entirely and the
|
|
proxy gets ECONNREFUSED. Wildcard binds still proxy via loopback because
|
|
both processes share the host.
