<nc-section data-title="Version 1" data-color="red"> Thunder slowed to a restless trot as we approached the stables. A broad-shouldered knight waited beneath the lanterns, his silvered armor bearing the crest of a crimson lion. “You must be Frederick,” he said, taking the reins with a gauntleted hand. His stern face softened into a faint smile. “I am Sir Roland. Welcome to the castle—and to the beginning of your training.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick dismounted near the stables, his legs unsteady after the long journey. Before he could call for a groom, a weathered knight emerged from the shadow of the hayloft. A green cloak hung from his shoulders, fastened by a clasp shaped like a dragon’s wing. “Frederick?” the knight asked. “Yes, sir.” “Sir Roland,” the man replied, extending his hand. “I was beginning to wonder whether the road had swallowed you.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick guided Thunder toward the stables, the stallion suddenly halted and snorted. A lone knight stood beside the open doors, his hand resting casually on the pommel of his sword. “Easy,” the stranger murmured, and Thunder quieted at once. Frederick stared in surprise. The knight gave him an amused look. “A squire should know his horse before he dreams of knowing battle. I am Sir Roland, and unless fortune has played me false, you are Frederick.” </nc-section>
