<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick was met by Sir Roland, a broad-shouldered knight with a weathered face and a calm, appraising gaze. The knight dipped his head in greeting and said, "You must be the young squire I've been told about. Come—if you mean to serve here, you'll learn that a castle is not only stone and steel, but discipline, patience, and hard work." </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick approached the stables, a tall figure in polished mail stepped from the shadows of the hayloft. Sir Roland smiled beneath his silvered helm and clapped a hand against the nearest stall door. "You have good timing, lad," he said. "The horses are to be fed, brushed, and readied before dusk. If you can earn their trust, you'll earn mine as well." </nc-section> <nc-section data-title="Version 3" data-color="blue"> The smell of straw and horse sweat filled the air as Frederick neared the stables, where Sir Roland waited beside a dapple-gray mare. The knight's voice was warm, though stern. "Frederick, is it? I've heard you came with eager hands and a willing heart. Good. You'll need both, for a squire's first lessons often begin where the muck is deepest and the work is hardest." </nc-section>
