平时做威胁建模看多了乱七八糟的架构图，反而特别想生点极度干净的画面透透气。这张就是奔着零软阴影去的，一个空心立方体当王座，一道刀刃一样的白光劈下来，地面反射把影子拉成一张线性网，构图我强制切成数学象限，多一点柔化就废了。
提示词我在原意上补了材质和反射细节，负面把柔光和杂物清干净：
minimalist high-angle graphic-design study of an avant-garde concept throne room,
the throne reduced to a pure sharp-edged hollow cube of blackened structural steel,
seamless pristine matrix of highly polished white Carrara marble tiles, zero-bleed alignment joints, mirror-like floor reflection,
composition split into strict mathematical quadrants, maximal geometric abstraction,
a single razor-thin blade of intense white light slicing straight down, casting a long distorted yet perfectly linear shadow network across the reflective plates,
zero soft shadows, absolute mathematical cleanliness, functionalist architectural rationality, cold neutral palette
Negative: soft glow, ambient occlusion haze, clutter, decorative ornament, warm tint, texture noise
那道光的宽度我调过很多次，太宽就没有刀刃感了，窄一点冷一点更对味。
