        <p>This is FAI Fuzer medium v0.3, an updated version of our previously released Fuzer v0.1. In this version, we've introduced several enhancements, including the addition of a new anime model to broaden your creative possibilities.</p>
        <p>We appreciate the feedback and support from our community and are excited to bring these new features to you.</p>
        <p><strong>What's New in v0.3:</strong></p>
        <ul>
            <li>🚀 Introduction of an Anime Model: Now you can choose between "realistic" and "anime" styles for your images.</li>
            <li>🎨 Enhanced Control: Improved background blending and consistency features.</li>
            <li>📈 Performance Improvements: Faster processing and improved UI responsiveness.</li>
        </ul>

        <h2>Step-by-Step Instructions</h2>
        <p>Follow these instructions to control the generation of backgrounds while keeping the foreground's shape and style consistent:</p>
        <ul>
            <li>
                <span class="emoji">📝</span>
                <strong>Step 1: Describe the Background</strong>
                <p>Start by providing a detailed description of the background you want to create.</p>
                <div class="example">
                    <p><strong>Example:</strong> "A Perfume Bottle nestled on a crystalline cliff of glistening snow, overlooking a serene, moonlit valley."</p>
                </div>
            </li>
            <li>
                <span class="emoji">💡</span>
                <strong>Step 2: Describe the Foreground</strong>
                <p>Next, describe the texture, lighting, and style of the foreground element.</p>
                <div class="example">
                    <p><strong>Example:</strong> "A transparent glass perfume bottle, vibrant, sunset lighting reflecting off its surface."</p>
                </div>
            </li>
            <li>
                <span class="emoji">🎚️</span>
                <strong>Step 3: Adjust the Intensity</strong>
                <p>Decide how much change you want to apply to the image. Adjust the intensity to balance between keeping consistency and introducing new elements.</p>
            </li>
        </ul>
        <p><strong>Note: It usually takes around 20 seconds to generate an image. However, the time can extend up to 40-50 seconds when there is a queue.</strong></p>
