<p>Upang mapanatili ang steady na 60 FPS habang nag-i-scroll ang user, gamitin ang modernong <code>contain</code> property kasama ang <code>IntersectionObserver</code> upang i-isolate ang rendering ng bawat card:</p>
<pre><code class="language-plaintext">// ui/catalogRenderer.js
const viewportWatcher = new IntersectionObserver((entries) =&gt; {
  entries.forEach((entry) =&gt; {
    if (entry.isIntersecting) {
      // I-load ang visual assets kapag pumasok na sa screen
      entry.target.classList.add('visible-card');
      viewportWatcher.unobserve(entry.target);
    }
  });
}, { rootMargin: '150px 0px' });

export function mountGameGrid(containerElement, gameDataList) {
  const fragment = document.createDocumentFragment();

  gameDataList.forEach((game) =&gt; {
    const card = document.createElement('div');
    card.className = 'game-card-wrapper';
    // Pigilan ang layout calculation sa buong page
    card.style.contain = 'content';
    card.dataset.id = game.id;

    fragment.appendChild(card);
    viewportWatcher.observe(card);
  });

  containerElement.appendChild(fragment);
}
</code></pre>
<ul>
<li><p><strong>Mga Benepisyo sa Mobile Viewport:</strong></p>
<ul>
<li><p>Isolated Browser Reflows: Ang mga pagbabago sa loob ng card ay hindi nagti-trigger ng re-calculation sa ibang bahagi ng web page.</p>
</li>
<li><p>Mababang CPU Usage: Ang mga imahe at dynamic animations ay nag-i-initialize lamang kapag malapit na sa visible area ng screen.</p>
