/* 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.
*/
document.addEventListener('copy', function (e) {
if (!e.clipboardData) { return; }
var selection = window.getSelection();
if (!selection) { return; }
var text = selection.toString();
var clean = text.replace(/\nCopy code\s*$/, '');
if (clean === text) { return; }
e.clipboardData.setData('text/plain', clean);
e.preventDefault();
}, true);
