  // 1) Block every element’s .focus()
  const nativeFocus = HTMLElement.prototype.focus;
  HTMLElement.prototype.focus = function() {
    // no-op: blocks ChatGPT’s auto-focus entirely

  // 2) Grab the native setter for <textarea>.value
  const valueSetter = Object.getOwnPropertyDescriptor(
    HTMLTextAreaElement.prototype, 'value'
  ).set;

  // 3) Listen for window.postMessage("your prompt")
  window.addEventListener('message', event => {

    // 4) Find the hidden React <textarea>
    const ta = document.querySelector('textarea.text-token-text-primary');
    if (!ta) return;

    // 5) Inject via native setter (no focus needed)
    valueSetter.call(ta, text);

    // 6) Click Send
    const sendBtn = document.getElementById('composer-submit-button');
