Paper Tear Flat Illustration Poster

Generate a vertical flat illustration poster centered on the theme "{argument name="theme" default="The sun stands at the door of the night"}". First, cover the canvas with a high-purity structural color derived from the thematic emotion, acting as a low-noise colored paper surface that provides occlusion, whitespace, and breathing room. Do not establish real depth or a full scene; instead, treat the background as a closed skin with slight paper texture, scanning grain, and minor printing irregularities. The main visual should not be fully displayed in front of the background but should emerge from an irregular horizontal rift torn from the upper-middle part of the paper surface. The rift should feature white paper fibers, dark inner edges, sharp jagged fringes, and a slight outward fold, as if the inner world is pushing the paper open. The theme is revealed from within the rift only through key cropped segments, recognizable edges, a small but intense focal point, and high-density fragments; the complete outline is swallowed by the paper, and secondary information is obscured, leaving only the physical tension, material texture, and symbolic core that best define the theme. The focal point area is small but must dominate the first glance like a point of gaze, semi-enclosed by a foreground shape. This occluding shape, transformed from thematic semantics, features gesture-like curves, close-up tactile quality, and horizontal guidance, covering part of the focus to create a visual resistance of being pushed open, discovered, or protected. Fragments derived from the theme gather at the edges of the rift, forming soft boundaries along the top, bottom, left, and right, partially overflowing onto the paper surface without spreading evenly; fragments are both content and part of the rift structure, pushing the internal world toward the external void through density, direction, and color dots. Color maintains clear hierarchies: the largest area of structural color remains pure, the rift interior uses medium areas of vital or material colors, and small highlights of emotional color flicker only near edges and the focus. Dark anchor points are placed at the focus outline, inner edges, and key occlusions, while the highest brightness is used only for torn edges, tiny highlights, and material cuts. The overall style is finished with hand-painted flat color blocks, clear blue-black or dark line drawings, slight paper grain, scanning noise, and uneven printing particles, allowing the object to be recognized by partial contours and density even while partially hidden. Retain significant solid color breathing room in the lower or quietest empty zones. If text appears, it should only serve as meticulous titles, numbers, short phrases, or miniature footnotes, using restrained publication typography with fine strokes, wide spacing, and low interference, collaborating with whitespace without distracting from the focus inside the rift. The entire image creates a cover-like feel where a solid-colored void suppresses the inner world while the rift exposes thematic secrets, stably maintaining order among the quiet paper, upper-middle break, high-density interior, single strong focus, foreground occlusion, edge fragments, dark anchors, and low-toned text.

以{argument name="主题" default="太阳就站在黑夜的门口"}为核心生成一张竖版平面插画海报，先用一个由主题情绪推导出的高纯度结构色铺满画面，让它像低噪声的彩色纸面一样承担遮挡、空白和呼吸；画面不建立真实景深和完整场景，而把背景处理成一层封闭表皮，表面只有轻微纸纹、扫描颗粒和细小印刷不均。主视觉不要完整陈列在背景前，而是在画面中上部由纸面撕出一道横向延展、略带斜势的不规则裂隙，裂口带白色纸纤维、暗色内缘、尖角毛边和轻微外翻感，像内部世界把纸面撑开。主题只通过被裁切的关键局部、可识别边缘、一个小而强的焦点和高密度碎片从裂隙内部显现；完整轮廓被纸面吞掉，次要信息被遮住，只留下最能说明主题的形体压力、材质触感和象征核心。焦点面积不大，却必须像凝视点一样支配第一眼阅读，被近景遮挡形体半包围；这个遮挡形体由主题语义转化而来，具有手势般的曲线、近距离触觉和横向引导力，覆盖焦点的一部分，让观看带有被拨开、被发现、被保护的阻力。裂隙边缘聚集由主题派生出的细碎形态，它们沿上下边和左右端形成软边界，局部外溢到纸面上，但不平均散开；碎片既是内容，也是裂口结构的一部分，应通过密度、方向和色点把内部世界推向外部空场。色彩保持清楚面积层级：最大面积结构色保持纯净，裂隙内部使用中等面积的主体生命色或材质色，小面积情绪亮点只在边缘碎片和焦点附近闪现，深色锚点压在焦点轮廓、内缘 and 关键遮挡处，最高明度只用于撕纸边、微小高光和材料切口。整体采用手绘平涂色块、清晰蓝黑或深色线描、轻微纸纹、扫描噪点和不均匀印刷颗粒完成，让对象像被纸面遮住后仍能凭局部轮廓、边缘取舍和局部密度被认出。下方或最安静的空白区保留大量纯色呼吸，文字若出现，只作为细致的题名、编号、短句和微型注脚，使用克制的出版物字体气质、细笔画、宽字距和低干扰层级，文字与空白协作，不抢裂隙内部的焦点。整张画面形成纯色空场压住内部世界、裂隙暴露主题秘密的封面感，稳定保留大片安静纸面、中上部破口、高密度内部、单一强焦点、前景遮挡、边缘碎片、暗色锚点和低声文字之间的秩序。背景色：{argument name="背景色" default="暗黑"}，比例{argument name="比例" default="16:9 横板"}
