<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight in polished mail raised a gauntleted hand. "You must be Frederick," he said, his voice steady as the evening wind. "I am Sir Roland. Thunder has carried you well—see that he is watered, then come with me. The castle does not wait on late arrivals." </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick had barely swung down from the saddle when a knight stepped out from the stable shadow, helm tucked beneath one arm. "Easy, lad," Sir Roland said with a wry smile. "I am Roland, and these stalls are my charge as much as the yard. Your horse looks half-wild with the road. Walk him cool, and then we will talk of what the king expects of a new squire." </nc-section> <nc-section data-title="Version 3" data-color="blue"> The smell of hay and oiled leather met Frederick at the stable doors. A knight waited there, cloak dusted with the day's ride, watching the banners fade into dusk. "Frederick," Sir Roland said, offering a firm clasp of the forearm. "Welcome to the castle. I am Sir Roland. Leave Thunder with the grooms—he has earned his rest—and walk with me. Training begins at first light, whether you are ready or not." </nc-section>
