UIGraph UI (uigraph-ui)

The UI is a static build served by nginx. At startup nginx substitutes these three URLs into its config and reverse-proxies browser requests to the backend services, so all three must point at reachable in-network addresses.

Variable	Required	Default	Description
UIGRAPH_API_URL	Yes	—	In-network base URL the UI proxies REST calls (/api/) to.
UIGRAPH_GRAPHQL_URL	Yes	—	In-network base URL the UI proxies GraphQL calls (/graphql) to.
UIGRAPH_GATEWAY_URL	Yes	—	In-network base URL the UI proxies gateway calls (/gateway/) to — this is what streams the AI chat. Without it the AI chat in the UI won't work.
