<nc-section data-title="Version 1" data-color="red"> Thunder slowed to a restless trot as Frederick neared the stables. A broad-shouldered knight stood beneath the arched doorway, his silvered mail gleaming in the last light. One hand rested on the pommel of his sword. “Frederick, I presume,” he said. “I am Sir Roland. Welcome to the castle—and to the end of your easy days.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The scent of hay and saddle leather greeted Frederick as he dismounted beside the stables. A weathered knight approached, carrying his helmet beneath one arm. A pale scar crossed his brow, but his smile was warm. “You must be Frederick,” he said, offering a calloused hand. “Sir Roland. I’ve been charged with your training. Let us hope you learn as quickly as you ride.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Before Frederick could call for a stable hand, a tall figure stepped from the shadows between the stalls. His dark cloak bore the castle’s golden crest, and a sword hung at his side. “So the new squire has arrived at last,” the knight said, studying Frederick with sharp gray eyes. “I am Sir Roland. See to your horse, then report to the training yard. Sunset is no excuse for idleness.” </nc-section>
