创作一张比例2:3的竖版万圣节静物展示背景。饱和紫色无缝墙地，细腻哑光立体渲染，柔光从左上照入。上半部保留大面积完整紫色空白，道具集中于下半部。 前景中央放一只低矮奶油白五角星形台座，后侧偏右为橙色竖向罗纹圆柱展示台，台面保持空置。右侧三支细长黑蜡烛高低错落，烛台分别用淡紫与桃橙色，有罗纹柱状底座，烛芯带小暖光。 左下是一只高瘦桃橙色南瓜，弯曲深色瓜蒂；南瓜后方竖一块淡紫色扇形波齿背板。地面前方散放少量橙色、粉色、紫色圆纸屑，数量克制，投影柔软自然。 几何物体比例清楚，表面圆润，保持台面的完整可用面积。不要文字、字母、标志、水印、蝙蝠群、人物、实际商品或外部边框。
Vertical 2:3 product-display background. Match the source image's overall composition, atmosphere, perspective, materials, and main display structures, while redesigning secondary decorative elements with related but visibly different shapes, positions, angles, and colors. Clean commercial stock-background quality. No watermark, logo, brand mark, readable words, letters, numbers, tiny edge text, UI marks, checkmarks, or disconnected white border. Create a warm creamy-beige studio with three simple circular ivory risers arranged across the lower third, a slim indoor palm on the left, and long diagonal sunlight shadows across the wall and floor. Minimal, calm, editorial product stage.
