<nc-section data-title="Version 1" data-color="red"> Frederick had barely dismounted when a stern voice called out from beside the stables. “Would you care to let that horse breathe before you flatter it with your staring?” Sir Roland asked, stepping into view with a grin beneath his helmet. Frederick straightened at once. “Forgive me, sir. I’m Frederick, sent here for training.” “Then you’ve come to the right place,” Roland said, clapping him on the shoulder. “A squire learns quickly here—or not at all. Come, we’ll see if you know a bridle from a battle cry.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Frederick was just untacking his horse when a tall knight in polished mail approached, his expression sharp but not unkind. “You must be the new squire,” Sir Roland said. “The stableboys told me to expect a boy with more dust on him than dignity.” Frederick flushed. “I meant no trouble, my lord.” “Trouble is useful if it teaches you something,” Roland replied. He glanced at the horse, then back to Frederick. “Feed him first. Then meet me in the yard. We begin with lessons your master should have already given you.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The smell of hay and leather filled the air as Frederick led his horse toward the stable doors. There, leaning against a post, stood Sir Roland, his arms folded and his gaze measuring. “So,” Roland said, “you’re the squire they’ve sent me. You look younger than the last one.” Frederick swallowed. “I’ll work hard, sir.” A faint smile touched Roland’s mouth. “Good. Hard work matters more than age. Leave your horse with the stablemaster, Frederick. If you survive your first week, I may even teach you how to hold a sword without looking like you’re wrestling a fish.” </nc-section>
