          To replace the screenshot with a video of the gameplay later:
          
          1. Remove the <img> tag below
          2. Uncomment and use the following <video> structure instead:
          
          <video autoplay muted loop playsinline poster="user_input_files/poster.jpg" class="phone-video">
              <source src="user_input_files/gameplay.mp4" type="video/mp4">
              Your browser does not support the video tag.
          </video>
          
          3. Add the following CSS for the video:
          .phone-video {
              width: 100%;
              height: 100%;
