<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight in a worn surcoat stepped into Thunder’s path and raised a gauntleted hand. “Easy, lad. I’m Sir Roland. You must be Frederick—the new squire. Stables first, then the yard. Leave the stallion with the grooms and come with me.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The smell of hay and oiled leather met Frederick as he slowed Thunder by the stable doors. A knight with silver at his temples smiled and took the reins. “Sir Roland, at your service. Welcome to the castle. You’ve ridden hard—walk him cool, then I’ll show you where squires sleep.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Before Frederick could dismount, a voice called from the stable arch. “Hold there.” Sir Roland emerged, helm under one arm, and studied the boy with a measuring look. “Frederick, is it? Good. I’m Roland. The king expects courage, not ceremony. Stable your horse, then report to me by the training posts before the light fails.” </nc-section>
