黎明前，玄武岩峽谷裡留一條藍色河流

A broad basalt canyon before dawn. Near hexagonal black columns frame a faintly glowing turquoise river; natural rock arches span the distance, fine mist separates cliff layers and one warm star remains in the violet sky. Game-engine-quality physical materials, wide cinematic composition with breathing room at center. No creatures, text or logos.

黎明前的廣闊玄武岩峽谷，近處六角形黑色石柱框住一條微亮青藍河流，遠處天然巖拱跨過峽谷，薄霧分出多層山壁，紫色天空剩一顆暖星。遊戲引擎級物理材質渲染，寬畫幅、中心留視覺呼吸，不要生物、字或標誌。
