雾的密度调低一档，暗部才不吃噪点
红光只做侧key，雾层负责透光，噪点和光晕都得压着，跟调渲染参数一个道理。
✍️ 留白不是留空的，另一侧刻意把雾压到最低、渐变收干净，这跟给图标腾位置是同一个函数。密度和噪点两个变量互相牵制，调猛了就变噪片。

A 16:9 widescreen cinematic-atmosphere wallpaper, built for an OLED-friendly, mostly dark canvas: near-black space holds subtle red gel-lit fog shaped into elegant volumetric ribbons, with one dominant flow line sweeping diagonally across the frame and layered wisps that feel slow, intentional, and airy. Fog density stays low throughout, so darkness still dominates.
Light it like a controlled studio haze test: a soft red side key reveals the fog's translucency, with faint edge highlights and deep charcoal shadow pooling inside the layers. Add only extremely sparse particulate shimmer and micro-grain, just enough for the haze to read as physical rather than noisy, and keep any glow bloom restrained and smooth — never neon-sharp.
Reserve a broad negative-space plate on the opposite side of the frame, where fog stays minimal and the gradient runs clean and dark. Let the fog concentrate in a single region so the whole composition feels designed and icon-friendly, staying fully abstract and unmarked — no objects, no typography cues anywhere.

这是一张16:9宽屏的电影氛围壁纸，专为OLED屏幕设计的深色主导画面：近乎全黑的空间里飘着一层淡淡的红色胶片雾，被塑造成一道道优雅的体积感丝带，一条主导的气流线斜穿画面，配着几缕层叠的雾丝，慢、克制、轻盈。雾的密度始终偏低，让画面整体维持深色基调。
打光手法像一次受控的棚拍雾测：一道柔和的红色侧光揭示出雾的透光性，边缘打出细微高光，雾层内部沉着深炭灰色阴影。只加入极其稀疏的颗粒闪烁和微粒质感，刚好让雾气读起来像实体而不是噪点，光晕控制得克制而顺滑——绝不做成霓虹式的锐利光斑。
画面另一侧特意留出大片留白区域，那里的雾维持在最低限度，渐变干净而深沉。让雾集中在单一区域，使整体构图显得经过设计、便于放图标，画面始终保持抽象、不带任何标记——没有具体物体，也没有排版文字的暗示元素。
