<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight in polished mail stepped into Frederick's path. "You must be the new squire," he said, offering a firm handshake. "Sir Roland. Thunder looks well-ridden. See him watered, then report to the yard before the light fails." </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick swung down beside the stable doors just as Sir Roland emerged from the tack room, a curry comb still in hand. The knight's weathered face broke into a grin. "Frederick, is it? Welcome. I've been expecting you. Walk with me—there's hay to turn and a lesson or two before supper." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Lanterns were already lit along the stable aisle when Sir Roland called out from the shadows. "Hold, lad. Name's Roland. The castle can wait a moment." He clapped Frederick on the shoulder and nodded toward Thunder. "A fine animal. Unsaddle him properly, and I'll show you where the squires sleep." </nc-section>
