GPT Image提示词：

A solitary white door stands upright in the middle of a wide, windswept field, with no wall or structure around it. Tall grasses bend in soft waves toward the horizon, and tiny wildflowers gather at the base of the door. Through its slightly open frame, a quiet band of warm light reveals a different landscape: a pale, misty valley beneath a clear sky. The surrounding field remains cool green and silver, creating a restrained contrast with the amber glow beyond the threshold. Frame the door slightly off-center in a broad horizontal composition, allowing the empty landscape to carry the sense of scale and silence. Low late-afternoon sunlight casts long, delicate shadows across the grass. Dreamlike but believable, minimalist cinematic photography, natural textures, atmospheric depth, crisp focal detail, balanced color, high-resolution fine art image.

中文提示词：

一扇孤立的白色门竖立在辽阔旷野中央，四周没有墙体或建筑。高草随风形成柔和波浪，门脚散落着细小野花。微开的门框后透出一片温暖光带，隐约显现淡雾山谷与晴朗天空。眼前草地呈清冷的绿与银灰，和门后的琥珀色微光克制对照。门略偏画面一侧，横向宽阔构图让空旷景色呈现静默尺度。傍晚低角度阳光在草地投下细长柔和的影子。整体梦幻而可信，极简电影摄影感，自然质感，空气层次清晰，焦点细腻，色彩平衡，高分辨率艺术影像。

说明：草原风向同一方向倾斜，白门后的暖光暗示另一处风景。
