這張旅行海報，穩得押韻不飄
上半留白下半原圖，一冷一熱，像副歌前的鋪墊。
✍️ 磁貼寬度卡在20%到30%，這是唯一的硬槓槓，大了搶戲小了沒存在感。主色不能自己挑，必須從原圖裡現取，不然上下兩截接不上氣口。

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.

做一張嚴格豎版3:4佈局、上下兩段等分的高階旅行海報，唯一的素材來源是使用者上傳的旅行照片——先判斷畫面裡唯一的主體是人物、地標建築還是風景。上半部分：從照片裡直接取樣的一種主色調鋪滿大片留白，放一枚從主體上精確提取的小型琺琅紀念磁貼（佔寬度20%-30%），輪廓、視角、比例、顏色和細節都要照抄原圖，底下壓一層自然陰影，外框是一圈細細的米白色描邊。磁貼下方，只有在能確認地名時才加一行[文字風格：優雅手寫體]的英文[地名：地點名稱]，不確定就不加。下半部分：原始照片保持完全不動，只允許自然裁切——不許重繪、不許生成、不許變形、不許刪物體、不許改變主體身份。
