+/* Fix: Prevent "Copy code" button label from appearing in clipboard content.
+ *
+ * sphinxawesome_theme inserts a copy button inside <pre> elements. When
+ * clipboard.js selects all children of the <pre> to copy, the button's
+ * sr-only text ("Copy code") is included in the selection. This listener
+ * intercepts the copy event and strips that trailing label from the data
+ * written to the clipboard.
