<nc-section data-title="Version 1" data-color="red"> I led Thunder through the castle gates and toward the stables, where a broad-shouldered knight was inspecting a row of horses. He turned at our approach, his silver spurs catching the last light. “Frederick, I presume?” he said. “I’m Sir Roland. Welcome to the castle.” He offered me a hand, then glanced at Thunder. “You’ve made good time. See your horse settled, and I’ll show you where you’ll be sleeping.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder shied as a hammer rang against an anvil near the stables. I tightened the reins, but a knight stepped from the shadows and held out a calm hand. “Easy there,” he murmured, and Thunder lowered his head to sniff his fingers. The knight smiled at me. “Sir Roland. You must be Frederick, the new squire.” “I am, sir.” “Good. Let’s get him fed before we talk about tomorrow’s training.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> I had barely dismounted beside the stables when a voice called, “You’re later than I expected.” A knight stood in the doorway, his dark cloak dusted with straw. He studied me for a moment, then gave a short nod. “Sir Roland,” he said. “And you’re Frederick.” “Yes, sir.” I tried to hide my unease as he approached. “Don’t look so worried. Your first lesson can wait until morning.” He took Thunder’s reins and led us inside, where the smell of hay and warm horses softened the chill of the evening. </nc-section>
