美食海报，采用分体式照片/插画设计

干净现代的方形美食海报，以 {argument name="food item" default="圣诞布丁"} 为主题，置于纯色 {argument name="background color" default="红色"} 背景之上。一道锐利的垂直白色分割线将构图一分为二，把主要对象分成等份。左半部分展示了主菜的超写实照片，具有真实的表面细节、逼真的色彩和自然的光照，在中间分割线处精确裁剪。右半部分则转变为极简的轮廓插画，与照片一侧的形状和主要特征完全相同，保持一致的比例和视角。插画部分周围散布着异想天开的白色手绘元素和手写风格的排版，写着“{argument name="label text" default="节日美食"}”，线条粗细保持一致——融入了指示箭头、动感线条和与菜肴相关的基本组成图形。整体留白充足，背景色调统一，柔和的影棚光线均衡，阴影极少，现代商业设计风格，无人，以物体为中心的构图。

**Original English:**
Clean contemporary square culinary poster featuring {argument name="food item" default="Christmas pudding"} against a flat {argument name="background color" default="red"} backdrop. A razor-sharp vertical white divider cuts directly down the middle of the composition, separating the primary subject into equal portions. The first half displays a hyper-realistic photograph of the main dish with authentic surface details, true-to-life coloring, and natural illumination, precisely trimmed at the midpoint divider. The second half transforms into a minimal outline illustration that mirrors the identical shape and key features of the photographed side, keeping consistent scale and viewing angle. Surrounding the illustrated portion, scatter whimsical white sketched elements and casual handwritten-style typography stating “{argument name="label text" default="Festive Treat"}” using matching line thickness—incorporate directional pointers, dynamic streaks, and basic component graphics tied to the dish. Generous blank space throughout, uniform background tone, balanced diffused studio brightness, minimal shadow presence, contemporary commercial design style, human-free, object-focused composition.
