Rare Idiom Light Poetry

Centered on the "{theme}," create a minimalist, high-end, poetic, and quiet light and shadow poster. The image does not directly depict the theme, but transforms it into a "silhouette illuminated by light." Place a recognizable luminous container in the center of the image: {fan window / moon cave door / rectangular window light / arched niche / circular light window / screen projection / rounded corner luminous panel}. This shape resembles a beam of light cast onto a textured wall or paper, with soft, shiny edges and a slight misting diffusion. 

Inside the light-emitting container, use silhouettes and soft-focus projections to represent theme-related elements: {main element}, {symbolic element}, {environmental element}. The main silhouette is slightly clearer, while the secondary elements are more blurred, such as tree shadows, flower shadows, smoke, branches and leaves, lines, or object outlines projected through the paper window. All elements should be restrained, avoiding realistic details, only keeping the most distinctive contours. The image should have plenty of blank space, centered composition, and clear visual layering: the background is the quietest, the light zone is most eye-catching, and the silhouette has the most storytelling feel. 

Use low-saturation {background colors} for backgrounds, featuring delicate paper textures, wall grains, faint noise, slight gradients, and soft vignetting. Use {light colors} for light areas, such as cream white, ivory white, light gold, moonlight yellow, or cool white lowlights. Silhouettes use {silhouette colors}, such as ink gray, blue-gray, deep brown, charcoal, or monochrome dark tones. Keep overall color choices within three to four to create a quiet, restrained, and sophisticated color relationship. 

Overall style: Eastern aesthetics, modern minimalism, poetic posters, art exhibition visuals, magazine cover-level composition, soft light, negative shapes, silhouettes, blank space, airiness, delicate grains, low-saturation color schemes, quiet emotional tension. Avoid complex backgrounds, strong saturated colors, hard-edged lighting effects, over-realism, cluttered elements, and cheap decorations. The final image should be like "a poem left by light on the wall."
