<nc-section data-title="Version 1" data-color="red"> Frederick had barely crossed the yard when a broad-shouldered knight emerged from the stables, his polished mail catching the last light of day. “You must be Frederick,” Sir Roland said with a friendly grin, extending a gloved hand. “Welcome to the castle. If you’re to become a proper squire, you’ll begin by learning the care of horses before you ever set foot in armor.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Frederick was halted by a stern voice. Sir Roland stood beneath the timbered overhang, arms folded, watching him with sharp but not unkind eyes. “So, the boy from the village has arrived,” the knight said. Then his expression softened. “Come along, Frederick. A squire’s first duty is to know the beasts that carry his lord into battle.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick approached the stables, a knight in silver-trimmed armor stepped out, brushing straw from his gauntlet. Sir Roland offered a courteous bow and studied the young squire with quiet interest. “You’ve come at a fine time,” he said. “The horses are being settled for the night, and that makes this the best moment to learn. Walk with me, Frederick, and I’ll show you where your training begins.” </nc-section>
