创作一张比例16:9的横版万圣节商品展示背景。统一的暖橙色无缝墙地，柔光立体棚拍渲染，细腻哑光材质。主体集中在右半部，左半部保留大面积干净橙色留白。 右后方竖立一大一小两块圆顶拱形背板，均带等距竖向凹槽，大背板较高，小背板前置偏右；部分弧边有光滑外框。拱形前方是一只宽而低的橙金色圆形展示台，带薄薄的台阶底座，台面完整空置。 右后角聚两只不同大小的橙色南瓜，一只圆脸发暖光，一只保留自然瓜形。展示台前左放两颗大号橙白旋纹包裹糖果，三只黑色小蝙蝠聚在背板左上方。道具均不遮挡台面。 光从左上照入，地面投影细长柔和，空间简洁、前后层次清楚。不要文字、字母、标志、水印、人物、实际商品或样机边框。
Use case: product-mockup. Reference image: elegant white arch, round podium, and tropical leaf shadow composition only. Create a clean vertical 2:3 minimalist white display scene with a wide shallow ivory circular podium centered in the lower third, a large white arched wall feature behind it, partial architectural blocks at both lower sides, and soft palm fronds entering from both side edges to cast long subtle shadows. Use high-key neutral daylight, refined 3D studio render. Keep the podium empty. Change arch curvature, podium thickness, leaf positions, block shapes, wall texture, and shadow direction so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, brand mark, tiny edge text, border, or blank margin.
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, price tag, UI marks, checkmarks, or disconnected white border. Create a refined monochrome ivory studio with a giant arched recess in the back wall, a low pale-cream circular display podium in the foreground, a small matte-white sphere to the left, and deep-green palm fronds entering from both upper side edges. Soft diagonal leaf shadows and a calm empty center.
创作一张比例2:3的竖版万圣节商品展示背景。紫色无缝墙地，柔和渐变，干净的立体棚拍渲染风格，表面细腻哑光。中央后方是一道高圆顶拱门背板，浅紫色内面、细铜金色边缘，拱内保持完全空白。 前景中央放三级奶油白扁圆展示台，每层边缘有细铜色线，台面宽阔平整且不摆商品。左侧有一只高瘦桃橙色南瓜和一支黑色细蜡烛，右侧有两只圆胖桃橙色南瓜及一支高黑蜡烛，烛台为不同形状的罗纹底座。 拱门右上沿飞两只紫黑色小蝙蝠，地面前方零散放三颗紫橙包裹糖果。主光从左上照入，形成柔和长投影，铜边只有克制高光，南瓜纵向纹理清楚。 构图中轴稳定，道具围绕台面而不侵占展示区。不要任何文字、字母、标志、水印、商品、人物或外部边框。
