      <h2>About City Hours</h2>
      <p>
        City Hours is an independent magazine about the ordinary hours of city life —
        the routes we repeat, the rooms we share, and the small repairs that keep a
        neighborhood running. All stories, people, and places here are fictional.

  <dialog class="detail" id="detail-dialog" aria-labelledby="detail-title">
    <div class="detail__inner" data-testid="detail">
      <!-- filled by JS -->
    </div>
  </dialog>

  <script src="app.js"></script>
</body>
</html>
```

Wait detail container needs data-testid="detail" and data-id, complete title, full body. The dialog has inner div with data-testid. When open, set data-id on inner. But evaluation may look for [data-testid="detail"] with data-id. Good. Also "Do not leave invisible layers blocking" - dialog closed by default.

But evaluation might check detail is visible. dialog.showModal() creates backdrop. Fine.

Need ensure data-testid="detail" element has data-id. We'll set.
