Nano Banana Pro 的魔法光影幻觉提示词

夕阳下，平坦原野上孤零零的一棵树。幻象：树的影子比正常情况更暗，但影子里嵌着柔软发光的斑块，形状像树叶，光在影中，这不可能。仿佛影子是一个储存阳光的容器。发光的斑块只在影子内部的草叶上投射出微弱的光线，形成微焦散。影子之外，没有光芒。树本身看起来很普通；只有影子是神奇的、有形的。保持场景极其简单：地平线、树、影子、天空渐变。照片般真实的草地细节，梦幻而又扎实，一个不可能的规则改变带来“哇”的惊叹。

**Original English:**
A single tree on a flat field at sunset. Illusion: the tree’s shadow is darker than normal, but embedded inside it are soft glowing patches shaped like leaves, light inside shadow, impossible. As if the shadow is a container that stores sunlight. The glow patches cast faint light onto grass blades within the shadow only, making micro-caustics. Outside the shadow, no glow exists. The tree itself looks ordinary; only the shadow is magical-physical. Keep the scene extremely simple: horizon, tree, shadow, sky gradient. Photoreal grass detail, dreamy but grounded, “wow” from one impossible rule change.
