  "prompt": "A steam train races across an endless desert at sunset while a masked female outlaw rides beside it on a black horse. She leaps onto the moving train, fights her way across the roof, and reaches a guarded carriage carrying a frightened young prisoner. As soldiers surround them, she cuts the carriage loose, sending it down a different track toward a distant canyon. Epic western action film, fast-paced camera movement, dynamic horseback tracking shots, dramatic close combat, sweeping aerial views, flying dust, golden sunset, practical stunt realism, anamorphic lens flares, cinematic scale.",
