使用上传的旅行照片作为唯一真实来源，制作一张高端奢华旅行海报。首先分析照片，仅从中选择一个主要主体：人物、地标/建筑或风景。

Create a premium luxury travel poster using the uploaded travel photo as the single source of truth. Analyze it first and select one primary subject only: Person, Landmark/Architecture, or Landscape. Use a strict vertical 3:4 layout, split into two equal horizontal sections. Upper half: use one dominant solid color sampled from the photo, with generous negative space. Place one small, realistic die-cut enamel souvenir magnet (20–30% width) extracted directly from the original subject, preserving its silhouette, viewpoint, proportions, colors, and recognizable details. Add a soft natural shadow and thin cream/white border. Beneath the magnet, add one elegant handwritten English location/name, only if confidently identifiable; otherwise omit it. Lower half: keep the original photograph completely authentic, allowing only natural cropping. No repainting, regeneration, distortion, object removal, or identity changes. Style: luxury editorial travel postcard, museum souvenir, refined, minimal, timeless, premium paper texture. Negative: multiple magnets, invented scenery, gradients, illustrations, collage, fake text, logos, watermark, subject changes, face replacement, distorted architecture, regenerated photo.
