Over plain http (ComfyUI on a LAN address) the page has no Clipboard API, and the optional-chained write resolved without copying anything, so the buttons showed a success they had not earned. One shared helper now falls back to the copy command and says whether the text really reached the clipboard; the buttons show a failure mark when it did not.
