创作一张比例2:3的竖版万圣节插画展示背景。整体为深紫色夜景，柔和的绘画式立体空间，少量暖橙与金黄光源。中央是一块大紫色圆形背板，其前为宽橙色低圆台，背板与台面干净平整，供后续放商品和文字。 右上有一轮大金黄色满月，几只黑色小蝙蝠飞过。左上远景是尖顶小城堡和蜿蜒石径，左右用卷曲枯枝、细铁栅栏与岩石植物围出纵深。右侧树枝悬一只暖光灯笼，稍低处另有小灯笼。 前左放两支米白色粗蜡烛，前右是一组高矮不同的浅橙色瓜和少量秋叶。近景石块与植物较暗，月光和烛光只照亮必要边缘，让中间空白展示区保持明亮而不喧闹。 柔和层次、细腻笔触、适量雾气，清楚区分前景、中景与远景。不要文字、标志、水印、人物、实际商品或样机边框。
Create a polished vertical 2:3 commercial product display background with an empty product placement area or central display platform, clean full-bleed composition, refined studio lighting, high-quality 3D render or photorealistic product-photography finish, decorative elements that are related to the scene theme but not copied exactly, adjusted colors, positions, angles, proportions, and small details, no readable text, no numbers, no Chinese characters, no watermark, no brand logo, no trademark symbols, no tiny edge text, no dirty edge, no disconnected blank margins, and no border.
