<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped into the fading light and raised a hand in greeting. “You must be Frederick,” he said. “I’m Sir Roland, and I’ve been expecting you.” Frederick swung down from Thunder’s saddle, his legs unsteady from the ride. Sir Roland clasped his shoulder with a firm, reassuring grip. “Come along, lad,” the knight said. “The castle is full of lessons, but the first is simple: a squire should know his way around the stables.” </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. Beside them waited a knight in a weather-worn green cloak. “Frederick?” he called. “Sir Roland. Welcome to the castle.” Frederick bowed, suddenly aware of the dust on his boots. The knight’s stern expression softened as Thunder snorted and nudged his sleeve. “Ah, you’ve brought a spirited companion,” Sir Roland said. “Let’s get him settled. There’ll be time enough for introductions once the horses are fed.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged from between the stables, his polished armor catching the last blue light of the evening. He rested one hand on the pommel of his sword. “Frederick, I presume,” he said. “Sir Roland, at your service.” Frederick offered a respectful bow. Before he could answer, Thunder stamped and tossed his head, uneasy at the clatter of hooves from inside the stable. Sir Roland glanced toward the darkened stalls. “Best bring him in quietly,” he murmured. “Something has frightened the horses.” </nc-section>
