<nc-section data-title="Version 1: The Knight's Stern Greeting" data-color="red">As Frederick dismounted near the stables, a tall knight approached with measured steps. "Squire Frederick? I am Sir Roland. Your training begins at dawn. Fail me once and you’ll find yourself mucking stables until winter's end." His gaze lingered on the stallion's sweat-streaked flanks, judgment already written in his eyes.</nc-section> <nc-section data-title="Version 2: The Knight's Warm Welcome" data-color="green">Sir Roland stepped from the shadows of the stables with a broad, weather-worn grin. "Welcome, young Frederick! I'm Sir Roland, and these stables are my second home. Let’s get Thunder settled and then I'll show you the training yard—there's a sword there with your name on it if you're willing to earn it."</nc-section> <nc-section data-title="Version 3: The Knight's Cautious Greeting" data-color="blue">From the stall doorway emerged Sir Roland, cloak dusted with hay. He studied Frederick silently for a moment, then offered a curt nod. "Name's Roland. Keep your horse brushed and your questions short until you've proven yourself. The castle has no patience for the untested."</nc-section>
