咖啡品牌人物广告

生成一张 4:5 竖版咖啡品牌人物广告。中国男咖啡师穿白衬衫和深棕围裙，站在精品咖啡馆吧台后，正在向无字陶瓷杯中倒入拉花牛奶，旁边有无标签咖啡豆罐、磨豆机、木质托盘和一束晨光。背景是柔焦咖啡机、木架和绿植，不能出现菜单或店名。光线为温暖晨光加柔和室内补光，色调深棕、奶白、橄榄绿和黄铜色，干净有香气感。真实商业生活方式摄影，50mm 镜头，半身环境构图，手部动作自然、人物比例真实。画面内不要出现任何可读文字、logo、水印、杯身标签、菜单或品牌标识。

Create a 4:5 vertical coffee brand lifestyle portrait. A Chinese male barista in a white shirt and dark brown apron stands behind the bar of a specialty coffee shop, pouring milk for latte art into a blank ceramic cup. Nearby are an unlabeled coffee-bean jar, grinder, wooden tray, and a beam of morning light. Soft-focus espresso machine, wooden shelves, and plants in the background, with no menu or shop name. Warm morning light plus soft interior fill; dark brown, cream white, olive green, and brass tones, clean and aromatic. Real commercial lifestyle photography, 50mm lens, half-body environmental composition, natural hand action and realistic proportions. No readable text, logo, watermark, cup label, menu, or brand mark anywhere in the image.
