<nc-section data-title="Version 1" data-color="red"> As Frederick guided Thunder through the castle gates and toward the thatched roofs of the stables, a broad-shouldered man in half-plate armor stepped from the shadows between the stalls. The local knight, Sir Roland, raised a gauntleted hand in greeting. "Hail, young squire," he called, voice warm yet commanding. "I have been watching for your arrival. Come, let us see to your mount before the light fails entirely." </nc-section> <nc-section data-title="Version 2" data-color="green"> The last rays of sunlight painted the stable yard in gold as Frederick dismounted. Straw crunched beneath his boots while grooms hurried past with buckets and bridles. Before he could loosen Thunder's saddle, the local knight, Sir Roland, strode forward from the tack room, his cloak billowing. "Frederick, is it?" Sir Roland greeted him with a firm clasp on the shoulder. "The stable master told me a new squire was coming. You've chosen a fine hour to begin your training." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick's legs ached from the long ride as he led Thunder into the cool shade of the castle stables. Lanterns had already been lit, casting flickering shadows across the beams. From one of the stalls emerged the local knight, Sir Roland, his expression both welcoming and appraising. "So the new squire has finally reached us," he greeted, taking the reins with practiced ease. "I am Roland. Many trials await you here, but first we must speak of the road you traveled and what you may have seen along the way." </nc-section>
