<nc-section data-title="Version 1" data-color="red"> Frederick had only just dismounted when a broad-shouldered knight emerged from the shadow of the stables, his polished breastplate catching the last of the sunset. “You must be the new squire,” Sir Roland said, his voice deep but not unkind. He offered Frederick a firm hand. “Welcome to the castle. If you mean to serve well here, begin by learning the way of the horses—there is no finer teacher of patience than a restless steed.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Frederick slowed his pace as a knight in weathered armor stepped from behind a stack of hay. Sir Roland lifted a hand in greeting, a faint smile hidden beneath his mustache. “So,” he said, studying the boy with clear, steady eyes, “you are the squire they sent me. Good. We can always use someone with strong hands and a willing heart. Come—before the horses decide you are more nervous than they are.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick approached the stable yard, he was met by the clink of armor and the scent of straw and leather. Sir Roland stood beside the nearest stall, one hand resting on the carved hilt of his sword, the other extended in welcome. “You’ve arrived at a busy hour, lad,” he said warmly. “The horses are being groomed, the tack repaired, and every stable boy in the castle is pretending to work. You may as well join them—and prove you know which end of a brush belongs to the horse.” </nc-section>
