<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped into the fading light. His cloak was dusty from the road, and a silver stag gleamed on his breastplate. “You must be Frederick,” he said, offering a gloved hand. “Sir Roland. Welcome to the castle.” Frederick swung down from the saddle and clasped his hand. Behind them, Thunder snorted as a stable boy hurried over to take the reins. “I hope the journey was kind to you,” Sir Roland said, eyeing the horse. “Tomorrow, we’ll discover whether you’re as steady on your feet as he is on his.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling the warm scents of hay and leather into the evening air. A knight waited beside them, his gray hair tied neatly at the nape of his neck. “Frederick?” he called. “I’m Sir Roland. I was told to expect you.” Frederick dismounted, stiff from the ride, and bowed as best he could. Sir Roland returned the greeting with a smile and a firm pat on the shoulder. “Come along,” the knight said. “We’ll see Thunder settled, then find you something to eat. Castle life is easier to face on a full stomach.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick drew near the stables, a figure emerged from the shadow of the gatehouse. The knight wore no shining armor, only a travel-stained surcoat and a sword at his hip—but he carried himself like a man accustomed to being obeyed. “Frederick, I presume,” he said. “Sir Roland.” The older knight glanced at Thunder, then at the young squire. “A fine horse. Let’s hope his rider has the sense to keep out of trouble.” “I’ll try, sir,” Frederick replied. Sir Roland’s stern expression softened. “Good. The castle has enough trouble already. Come—I’ll show you where you’ll sleep.” </nc-section>
