Model response

<nc-section data-title="Version 1" data-color="red">
As I reined in Thunder near the stables, dismounting with a weary sigh, a tall figure emerged from the shadows of the hayloft. Sir Roland, the local knight, his armor glinting in the fading light, strode forward with a firm handshake and a gravelly voice. "Welcome to Castle Ebonheart, young squire Frederick. You've arrived just in time for supper—and the real trials begin at dawn."
</nc-section>
<nc-section data-title="Version 2" data-color="green">
Thunder's hooves clattered to a halt by the stables, steam rising from his flanks in the cool evening air. Before I could even tether him, Sir Roland appeared at my side, his weathered face breaking into a rare smile beneath his bushy mustache. "Frederick, is it? The tales of your journey precede you. Come, stable your mount and join me—there's much to discuss under these ancient walls."
</nc-section>
<nc-section data-title="Version 3" data-color="blue">
I guided Thunder into the stable yard, the scent of fresh hay and horses filling the air, when a commanding voice called out. Sir Roland, broad-shouldered and clad in a tunic emblazoned with the king's crest, approached with purposeful steps. "Hail, Squire Frederick. Your arrival is fortuitous; the castle stirs with whispers of unrest. Let us speak while you settle in—fortune favors the prepared."
