Minimalist Silhouette Greeting Poster

Drawing task: First, extract a core character that can be compressed into a silhouette or a single physical trace, then place it at the bottom of an extremely narrow, almost silent longitudinal image strip, surrounded by a large area of light gray empty space. The first impression must be a calm imbalance between the high and empty gray solid on the left and the sparse text on the right. The theme content appears only on a small scale at the bottom, as if weighed down by huge white space and time. Use a monochromatic grayscale, low contrast, matte paper, and fine-grain printing noise throughout. Soften the edges of the image slightly. Black is used only for a few strong anchors: small silhouettes, heavy main titles, numbers, or marks in the upper right. The text system is like architectural components rather than decoration. The main title uses an overweight geometric sans-serif structure, with short, thick strokes, flat-cut or rounded ends, and compressed character spaces, with occasional small stars or dots for rhythmic pauses. Sub-information is extremely small, thin, and loose, and can be placed vertically or off-axis to slow down the reading path. Change figures, objects, symbols, and text meanings when switching themes, but maintain the narrow image pillar, large open field, sparse black/gray anchors, paper grain, staggered levels, and sense of lonely commemoration. Avoid colorful decorations, dramatic lighting, full compositions, clean commercial layouts, overly clear retouching, and busy narratives.

画图任务：先提炼出一个可被压缩成剪影或单一实物痕迹的核心角色，再把它安置在一条极窄、近乎沉默的纵向影像带底部，周围保留大面积浅灰空白；第一眼必须是左侧高而空的灰色实体与右侧稀疏文字之间的冷静失衡，主题内容只在底部小尺度出现，像被巨大留白和时间压低。整体采用单色灰阶、低对比、哑光纸面与细颗粒印刷噪点，影像边缘轻微软化，黑色只用于少量强锚点：小剪影、粗重主标题、右上数字或标记。文字系统像建筑构件而非装饰，主标题用超重几何无衬线构造，笔画短厚、端点平切或圆化，字腔被压紧，局部可有小星点或圆点作为节奏停顿；副信息极小、细、松散，可竖排或偏轴放置，制造阅读路径的迟缓。主题转换时更换人物、物件、符号与文本含义，但保持窄影像柱、大空场、黑灰稀疏锚点、纸质颗粒、错位层级和孤独纪念感。避免彩色装饰、戏剧光效、饱满构图、整洁商业排版、过度清晰修图和热闹叙事。
