Geometric Milestone Celebration Poster

Create a geometric poster with a sense of commemorative ritual around {argument name="subject" default="any specific content"}: use a strong central axis to organize the reading flow, keeping about half of the frame as bright, relaxed light-colored white space with the {argument name="title" default="subject title"} suspended within it. Enlarge the most recognizable {argument name="short symbol" default="symbol"} of the theme into an overwhelming geometric bold visual anchor, making it step down from the white space into a tiered perspective memorial platform made of multiple horizontal color blocks. The memorial platform expands step by step from a narrow top near the visual center downwards and extends beyond the boundaries, forming a looking-up scale, a stable center of gravity, and a top-down ritualistic reading path. The giant symbol and the platform body share color and a vertical axis, appearing as both text and architecture, inseparable; the platform body is layered with modules of adjacent light and dark wide strips, each layer with clear edges, and soft dark bands are partially pressed against the joints to maintain the simplicity of the planar vector while producing a restrained step depth. The title uses upright, low-stroke-contrast Chinese sans-serif characters, with medium-thick weight and relaxed spacing; the subtitle is thinner and smaller, with significantly widened spacing and centered in lines; the giant symbol uses a heavy geometric skeleton, square ends, and compact internal space, becoming the first read from a distance. A minimalist light-colored silhouette badge refined from the theme is embedded in the middle of the platform, with slender dates or numbers arranged below it, followed by two lines of spaced short sentences to form a rhythmic pause; only low-contrast small signature information is kept in the corners and bottom edges, making the peripheral information subordinate to the central memorial structure. All specific hues are determined by the semantic meaning of the theme, with no fixed color names preset: the brightest, lowest-saturation light color of the theme serves as a large area background, and the deeper, high-saturation core color of the theme serves as the giant symbol and memorial platform. The core color progresses in homochromatic levels between the dark top, stable mid-tones, and brighter foreground; the text uses a dark version of the core color or reverses white from the light background. Small areas of high-brightness similar-colored circles dot the edges of the platform, and another larger, paler circular spot is cut from the edge of the white space to balance the hard geometry with a soft warm difference of no more than a small area. The background has a high-brightness diffused light and a fine paper fiber texture, with uniform particles spread in light-colored areas, and thin spray clouds superimposed at the edges of the white space and color block boundaries; printed color blocks retain slight ink absorption and transparent overlapping colors, with outlines remaining flat and clear, not forming stains or strong damage. The foreground can allow simplified badges derived from the theme to sink into the platform in a low-transparency, large-scale, partially cropped manner, vaguely appearing through a colored thin layer, enhancing depth without competing with the giant symbol. Finally, maintain an area order of light white space, giant symbol, and perspective platform at approximately half, nearly half, and very little embellishment, with an overall bright, gentle, and solemn feel; if the giant symbol and the platform body are separated, the peripheral information becomes heavy, the texture covers the outline, or the decoration increases, it will destroy this monumental cohesion.

围绕{argument name="主题内容" default="任意具体主题内容"}建立具有纪念仪式感的几何海报：以强中轴组织阅读，让画面约一半保持明亮、松弛的浅色留白，{argument name="标题" default="主题标题"}悬置其间；将{argument name="简短符号" default="主题最具识别度的简短符号"}放大为压倒性的几何粗体视觉锚点，使它从留白区向下跨入一座由多个水平色块搭成的透视纪念台，纪念台由靠近视觉中心的窄顶向下逐级扩展并延伸出边界，形成仰望式尺度、稳定重心与由上至下的仪式性阅读路径。巨大符号与台体共享色彩和垂直轴线，既像文字又像建筑，二者不可分离；台体用明暗相邻的宽条模块分层，每层边缘清晰，局部以柔和暗带压住接缝，保持平面矢量的简练，同时产生克制的台阶深度。标题采用端正、低笔画反差的中文无衬线字，字重中等偏粗、字距舒展；副标题更细、更小、明显加宽字距并分行居中；巨大符号使用厚重几何骨架、方整端部与紧凑内部空间，成为远距离第一读。台体中段嵌入由主题提炼的极简浅色剪影徽记，其下排列纤细日期或编号，再以两行疏朗短句形成节奏停顿；角落与底缘只保留低对比的小型署名信息，使外围信息服从中央纪念结构。由主题语义决定全部具体色相，不预设固定色名：最亮、最低饱和的主题浅色承担大面积背景，较深且高饱和的主题核心色承担巨大符号与纪念台，核心色在暗顶、稳定中间调和更明亮前景之间作同色系层级递进；文字使用核心色的深色版本或背景浅色反白，小面积高明度近似色圆形点缀悬于台体边缘，另一枚更大、更淡的圆形光斑从留白边缘被裁切，以不超过少量面积的柔和暖差平衡硬朗几何。背景呈高明度漫射光与细密纸纤维触感，浅色区域铺均匀微粒，在留白边缘和色块交界叠加轻薄喷点云雾；印刷色块保留轻微吸墨与透明叠色，轮廓仍平整清楚，不形成污渍或强烈破损。前景可让主题派生的简化徽记以低透明度、大尺度、局部裁切的方式沉入台体，像透过彩色薄层隐约显现，增强纵深却不争夺巨大符号。最终保持浅色留白、巨大符号、透视台体约为半数、近半数与极少点缀的面积秩序，整体明亮温和而庄重；若巨大符号与台体分家、外围信息变重、纹理覆盖轮廓或装饰增多，都会破坏这份纪念碑式凝聚力。
