Design a refined, high-end art poster/cover/key visual for the [theme/use], with the overall feel of a museum exhibition poster. The composition is dominated by a large area of warm off-white negative space, and the background carries a faint paper texture and soft print quality. On the right side or a diagonal region of the frame, build a large geometric color-block window. The default shape is a slanted-cut triangle, which can also become an irregular polygon, trapezoid, fan shape, or origami-like geometric facet depending on the theme. This geometric area is not an ordinary decorative color block but a "scenery window" that holds the world of the image: inside, use low-saturation, lightly misty, mineral-toned gradients containing [scene atmosphere/background elements], with restrained, clear, airy colors. Place the [core object] inside the geometric color block with real photographic texture or fine photorealism. The subject should merge naturally with the block but not be entirely trapped within it. Let parts of the [core object]'s contour, top, edges, branches and leaves, smoke, fabric, light and shadow, or structure naturally cross the geometric boundary and extend into the off-white negative space, creating frame-breaking, growth, spatial penetration, and breathing room in the image. Keep an asymmetric balance in the composition, reserving ample negative space on the left or top for title typography. Use restrained, exhibition-grade typography, with options such as a large vertical title, fine-print captions, minimal English subtitles, or a collection-label-style information hierarchy. Text color should be mainly ink black, dark gray, or dark green, avoiding a commercial-advertising feel. Overall style: high-end, quiet, generously spaced, Eastern aesthetics, modern art museum, exquisite printing, low-saturation colors, geometric cropping, real object breaking the frame, sense of natural growth, spatial penetration, minimal yet tense. The core object's color scheme should be vivid, striking, and full of life. —————— Theme this time: "A single rider gallops through the red dust, the concubine smiles; none know it is lychees arriving" Use: poetry appreciation Key visual elements: top-tier Japanese photography style, Instagram-filter texture, cinematic light and shadow, bright and translucent Other requirements: at least 4 knowledge points in the image, displayed across different levels, logics, and presentation schemes Use: poetry appreciation Window shape this time: equilateral triangle Background color: pure white patterned texture With each output, vary the layout, creativity, and hue Ratio 16:9 Use: teaching PPT slide, first slide
