<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped into the fading light. His silver cloak bore the castle’s crimson crest, and a sword rested at his hip. “You must be Frederick,” he said, offering a gauntleted hand. “I’m Sir Roland. Welcome to the castle.” Frederick swung down from Thunder’s saddle and returned the greeting. Before he could ask where to take the stallion, Roland’s eyes shifted to the horse—and narrowed at the strange, blue sparks flickering in its mane. “Tell me, squire,” the knight murmured, “has your horse always done that?” </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, tall and silver-haired, with a friendly smile beneath his neatly trimmed beard. “Frederick, I presume?” he said. “Sir Roland, at your service. I look after the castle’s horses—and the squires who arrive with them.” Frederick dismounted, grateful for the knight’s welcoming manner. Roland took Thunder’s reins, but the stallion shied from his touch and stamped the ground. For an instant, the stable lanterns dimmed. Sir Roland’s smile vanished. “That horse,” he said quietly, “has brought more than a young squire to our gates.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged from between the stable doors as Frederick rode up. The knight wore a weathered blue surcoat and carried himself with the easy confidence of someone who had spent a lifetime among horses and swords. “Welcome, Frederick,” he called. “Sir Roland. I was beginning to think the road had swallowed you.” Frederick dismounted, and Roland reached to steady Thunder. The stallion tossed his head, snorting at the knight’s outstretched hand. Roland paused, studying the horse with sudden seriousness. “So,” he said, lowering his voice, “the old prophecy was true after all.” </nc-section>
