💡 Idea
The publish docs explain "Because there is no sign-up, the topic is essentially a password, so pick something that's not easily guessable." I feel it would be neat to add a small script like such:

<script>
  // Generate a random UUID and remove hyphens
  const hex = crypto.randomUUID().replaceAll("-", "");
  // Convert hex string to bytes
  const bytes = new Uint8Array(hex.match(/.{2}/g).map((b) => parseInt(b, 16)));
  // Convert bytes to Base64
  let b64 = btoa(String.fromCharCode(...bytes));
  // Convert Base64 to Base64URL
  const b64url = b64.replace(/\+/g, "-").replace(/\//g, "_").replace(/=+$/, "");
  document.currentScript.replaceWith(
    "Here's a randomly generated topic just for you: " + b64url,
  );
</script>
