<nc-section data-title="Version 1" data-color="red"> Frederick swung down from Thunder just as a broad-shouldered knight emerged from the stable shadows. Sir Roland’s armor caught the last of the sunset, and he raised a gauntleted hand in greeting. “You must be the new squire,” he said, voice rough but warm. “Welcome to the castle. See that your horse is watered, then come find me—we start at dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, a knight in a travel-stained cloak watched Frederick dismount. Sir Roland stepped forward and clapped him on the shoulder. “Frederick, is it? Good. The stablemaster will take Thunder. I’ve been expecting you since the morning bell. Walk with me, and I’ll show you where the squires sleep.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The smell of hay and oiled leather met Frederick as he led Thunder toward the stalls. Sir Roland was already there, brushing down a gray destrier. He looked up and smiled. “Ah, the last of the new squires. I’m Sir Roland. You’ve ridden hard—rest your mount, then we’ll talk of what the king expects of you.” </nc-section>
