			<h1>MonoInk.js - Live Demo</h1>
			<p>Render web content with a retro screen effect. Use the controls on the right to see the effects in action!</p>

			<div class="demo-section">
				<h2>Quick Preview</h2>
				<p>MonoInk applies authentic retro computer display effects:</p>
				<ul>
					<li><strong>Pixelation</strong> - Chunky, low-resolution blocks</li>
					<li><strong>Dithering</strong> - Black/white dot patterns for grayscale simulation</li>
					<li><strong>High Contrast</strong> - Pure black/white conversion</li>
					<li><strong>Backlight</strong> - Vintage CRT monitor colors</li>
				</ul>
				<p><strong>Try it:</strong> Enable pixelation + dithering for the classic retro look!</p>

			<div class="demo-section">
				<h3>Sample Image</h3>
