这张旅行海报，稳得押韵不飘
上半留白下半原图，一冷一热，像副歌前的铺垫。
✍️ 磁贴宽度卡在20%到30%，这是唯一的硬杠杠，大了抢戏小了没存在感。主色不能自己挑，必须从原图里现取，不然上下两截接不上气口。

Build a premium travel poster in a strict vertical 3:4 layout split into two equal horizontal halves, using the uploaded travel photo as the only source of truth — first identify a single primary subject (person, landmark/architecture, or landscape). Upper half: a dominant solid color sampled straight from the photo fills generous negative space, holding one small, realistic die-cut enamel souvenir magnet (20-30% of the width) extracted from that subject with its exact silhouette, viewpoint, proportions, colors and details preserved, sitting on a soft natural shadow inside a thin cream/white border. Beneath the magnet, add [text style: elegant handwritten] English [location: location/name] only if it can be confidently identified — otherwise leave it out. Lower half: the original photograph stays completely untouched apart from natural cropping — no repainting, regeneration, distortion, object removal, or identity changes.

做一张严格竖版3:4布局、上下两段等分的高级旅行海报，唯一的素材来源是用户上传的旅行照片——先判断画面里唯一的主体是人物、地标建筑还是风景。上半部分：从照片里直接取样的一种主色调铺满大片留白，放一枚从主体上精确提取的小型珐琅纪念磁贴（占宽度20%-30%），轮廓、视角、比例、颜色和细节都要照抄原图，底下压一层自然阴影，外框是一圈细细的米白色描边。磁贴下方，只有在能确认地名时才加一行[文字风格：优雅手写体]的英文[地名：地点名称]，不确定就不加。下半部分：原始照片保持完全不动，只允许自然裁切——不许重绘、不许生成、不许变形、不许删物体、不许改变主体身份。
