Magical Shadow Illusion Prompt for Nano Banana Pro

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.
