Issue
Pixel writes complete without errors, but the displayed UI image does not change.
Cause
The ImageLabel may still reference the original asset, the editable content was not connected correctly, or writes target unexpected coordinates.
Fix
Follow the current content-object assignment workflow and prove the connection with one obvious solid-color edit. Confirm image dimensions and coordinate ranges. Batch changes rather than recreating the content object repeatedly.
Verify
Change a small corner to a distinctive color and confirm it appears at the expected orientation in Studio and a client test.
