Interactive Elements
When HTML has drafts or copy buttons, add this JS:
function saveDraft(el) {
localStorage.setItem('draft:' + el.dataset.threadId, el.textContent);
}
function copyToClipboard(text, btn) {
navigator.clipboard.writeText(text).then(() => {
btn.textContent = 'Copied!';
setTimeout(() => btn.textContent = 'Copy', 1500);
});
}
