黑底上流動的霓虹絲帶與卵形體
青色絲帶在左，暖橙高光落在卵形體上，上方留白給介面。
✍️ 真正有用的是“上方輪廓光把青色給絲帶、橙色給卵形體”這一句，顏色按物件分工，不是整體漸變，所以才有冷暖對話。負空間和裁切那句，是桌布題材該抄的實用經驗。

Rendering and surfaces: a 3D render built on PBR shaders, with smooth subdivision, high-sample lighting and physically plausible reflections. The ribbons and ovoids are glossy and semi-translucent, outlined by thin neon edge highlights and subtle micro-scratches; keep surface detail and micro-texture crisp. Please avoid faces, logos, visible text and heavy grain.
Light and environment: rim light from the top assigns cyan to the left-hand ribbons and warm orange to the ovoid highlights. Deep black dominates the background, set in a minimal studio with a subtle floor shadow and faint volumetric haze that adds depth.
Lens: camera slightly above, three-quarter angle, 85mm-equivalent focal length, moderate aperture; shallow depth of field gives smooth background bokeh, with no motion blur.
Content: abstract flowing ribbons and smooth ovoids composed as a 9:16 vertical wallpaper on a deep black canvas, with wide negative space left for UI cropping. Artistic, creative style, and high resolution output suitable for wallpaper.

9:16 豎版桌布：抽象的流動絲帶與光滑卵形體，漂浮在深黑畫布之上。表面半透明、有光澤，邊緣帶細細的霓虹高光和極淡的細微劃痕；表面細節與微紋理保持清晰。
鏡頭：略微俯視的四分之三角度，等效 85mm 焦距，中等光圈。淺景深，背景虛化順滑，沒有動態模糊。留出大面積負空間，方便被介面元素裁切。
光線：來自上方的輪廓光，把青色映在左側絲帶上，把暖橙色映在卵形體的高光上。背景以深黑為主，是極簡的影棚環境，帶淡淡的地面陰影和一層若有若無的體積霧以增加縱深。
渲染：3D 渲染，PBR 材質、平滑細分、高取樣光照與物理合理的反射。避免出現臉、標誌、可見文字和重顆粒。藝術創意風格，高解析度輸出，適合做桌布。
