+##### SetMouseoverUnit(unitToken)
+Sets the client's current mouseover unit from a unit token string.
+
+This uses the same client object-tracking path as normal UI mouseover updates. If `unitToken` resolves to a GUID, the mouseover is updated to that unit. If it does not resolve, the mouseover is cleared.
+
+**Parameters:**
+- `unitToken` (string): A standard unit token string such as `"target"`, `"party1"`, or `"mouseover"`
+
+**Returns:**
+- `1` if the client has a non-empty mouseover GUID after the update
+- `nil` if the mouseover GUID is empty after the update
+
+**Examples:**
+```lua
+SetMouseoverUnit("target")
+SetMouseoverUnit("party1")
+SetMouseoverUnit("mouseover")
+```
+
 ##### GetRaidTargets()
 Returns the current local raid-target assignments as a table of GUID strings.
