<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped into Frederick’s path. His scarlet cloak was clasped with a silver dragon. “You must be Frederick,” he said, offering a gloved hand. “I’m Sir Roland. Welcome to the castle—and I hope your horse is as brave as he is handsome. The stablemaster claims he tried to bite a groom.” Thunder snorted, as if offended. Roland laughed. “Good. A little spirit will serve you well here.” </nc-section> <nc-section data-title="Version 2" data-color="green"> A knight waited beside the stable doors, one hand resting on the pommel of his sword. His armor was worn, but polished bright enough to catch the sunset. “Frederick?” he asked. The young squire swung down from the saddle. “Yes, sir.” “Sir Roland,” the knight replied, nodding. “I’ve been expecting you. Give your horse to the stablehands, then come with me. There’s much to learn before the dawn—and the castle has a way of testing newcomers sooner than they expect.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A cheerful voice called from the stables. “You’ll want to slow that beast before he tramples the chickens!” A knight emerged, grinning beneath a neatly trimmed beard. “Sir Roland,” he introduced himself, giving Frederick a friendly bow. “And you must be the new squire.” Frederick glanced at Thunder, whose nostrils flared at the smell of hay. “He’s usually better behaved.” “Then he’ll fit right in,” Roland said. “The castle is full of folk who are better behaved on most days.” </nc-section>
