创作一张比例16:9的横版万圣节商品展示背景。统一暖橙色墙地，柔和哑光立体渲染。画面中下部排列三块橙色矩形展示台：左后较高、右后中等、前中最低，互相错开，台面宽阔平整且不摆商品。 右侧后方是一棵深棕色低多边形枯树，树干扭转，几组尖细枝杈伸向右上；树前放一只细长发光南瓜及两块棕灰岩石。最左侧后方放两块矮小灰米色墓碑，一块十字形、一块圆拱形，旁边点缀几簇黑色草。 前左是一只小圆发光南瓜和两颗紫橙包裹糖果，道具从左前到右后形成非对称框景。上半部保留大量橙色空白，中间展示台之间留有清楚间距。 主光从左上照入，阴影柔软，南瓜内光温暖而克制。不要人物、文字、字母、标志、水印、实际商品或外部边框。
Use case: product-mockup. Reference image: cool light-blue geometric setting with rough white plinth, circular wall form, and leafy plant only. Create a clean vertical 2:3 icy-blue and soft-lavender product display scene with tall fluted vertical panels on the far left, a leafy monstera in a tall white ribbed planter at lower left, a large pale-blue circular disc on the upper right wall, a low rough-textured white rectangular plinth in the lower center, and two small translucent blue glass spheres close to the floor edges. Keep the plinth empty. High-key polished 3D render with soft shadows. Change panel spacing, disc location, plant form, plinth texture, sphere sizes, and colors so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, brand, tiny edge text, border, or white margin.
