Minimalist poetic light-and-shadow Chinese idiom poster

With "{Theme}" as the core, create a minimalist, high-end, poetic, and quiet light-and-shadow poster. The image should not directly depict the theme, but instead transform it into "silhouette imagery illuminated by light." In the center of the frame, place a recognizable glowing shape container: {fan-shaped window / moon gate / rectangular window light / arched niche / circular light window / screen projection / rounded glowing panel}. This shape should feel like a beam of light cast onto a textured wall or paper surface, with soft glowing edges and slight misty diffusion.

Inside the glowing container, use silhouettes and soft-focus projections to express theme-related elements: {main element}, {symbolic element}, {environmental element}. The main silhouette should be slightly clearer, while the supporting elements are more blurred, like shadows of trees, flowers, smoke, branches, lines, or object outlines projected through a paper window. Keep all elements restrained, without realistic detail, preserving only the most recognizable contours. The composition should contain a large amount of white space, be centered, and have a clear visual hierarchy: the background is the quietest, the lit area draws the most attention, and the silhouette carries the strongest sense of story.

Use a low-saturation {background color} for the background, with fine paper texture, wall particles, subtle noise, slight gradients, and soft vignetting. Use {light color} for the illuminated area, such as cream white, ivory white, pale gold, moonlight yellow, or cool white shimmer. Use {silhouette color} for the silhouettes, such as ink gray, blue-gray, dark brown, charcoal black, or other dark tones in the same color family. Keep the overall palette within three to four colors, forming a quiet, restrained, and refined color relationship.

Overall style: Eastern aesthetics, modern minimalism, poetic poster, art exhibition visual language, magazine-cover-level composition, soft light, negative space, silhouettes, white space, airiness, fine grain, low-saturation color matching, and quiet emotional tension. Avoid complex backgrounds, highly saturated colors, hard-edged lighting effects, excessive realism, cluttered elements, and cheap decoration. The final image should feel like "a poem left by light on a wall."
