+## Display Integration
 
-When using Display service, help triggers this action:
-
-```go
-{
-    "action": "display.open_window",
-    "name":   "help",
-    "options": {
-        "Title":  "Help",
-        "Width":  800,
-        "Height": 600,
-        "URL":    "/#anchor",  // When using ShowAt
-    },
-}
-```
+The help window spec stays internal to the service. Callers initialize the help service with the display service and then call `Show()` or `ShowAt()`; the display layer opens the window from a declarative `window.Window` spec.
