Generate a 9:16 vertical editorial-style poster with an overall high-end, restrained, and elegant graphic design style. Warm ivory white paper background with slight natural paper texture and old-fashioned printing quality. The image adopts a clear point-line-plane composition: centered around 1 complete large circular main visual, paired with 4–6 geometric elements of different sizes such as circles, rings, or partial cross-sections, forming an asymmetrical longitudinal structure from top to bottom. Add fine textures related to the theme inside the circular surfaces, such as water ripples, rock layer patterns, glaze cracks, scent diffusion patterns, plant textures, etc., but the overall feel should remain 2D graphic, no 3D, no photographic collage, no e-commerce feel.

Add a small number of extremely fine vertical lines, arcs, or measurement lines as connecting and rhythmic elements. Place 1 small-sized concrete subject at the bottom or middle-lower part as a visual anchor, such as a vessel, a flower branch, a small installation, a specimen, or a character silhouette; the subject must not be too large and must not overpower the dominance of the geometric composition.

Arrange a large vertical Chinese title 【Title】 on the right side, with a slender, sparse font and ample white space; arrange extremely small text information in the left or middle-lower area, including 【Subtitle】, 【Activity Information】, 【Date and Time】, 【Location】, and a small amount of English information, creating an editorial contrast of "large characters extremely sparse, small characters extremely dense." The overall white space should be sufficient, the information density restrained, and the layout should resemble an independent publication or exhibition poster, rather than a template image.

Use a low-saturation color palette with the 【Main Color Tone】 at the core, which can be paired with 2–4 auxiliary colors; the colors should have hierarchy but not be overly gaudy. The overall temperament is quiet, literary, with a Japanese editorial and artistic feel. No numbering, no watermarks, no logos, no copyright text, no sparkles, no four-pointed stars.

Special requirements: The top main circle must be displayed in its entirety and cannot be cropped by the left or top edges; the background must completely cover the entire canvas, and no extra white margins or independent white columns should appear on the right; the image should look like a complete work, not like a placeholder template.

可替换内容：
【标题】如：山茶雅集 / 青屿香事 / 月汐诗会 / 岩层纪事
【副标题】如：一盏春山，半日清坐 / 风过林间，香留衣上 / 潮声入夜，诗句归岸 / 时间沉入石中
【活动信息】如：春茶品鉴 / 香氛研究 / 诗歌朗读 / 地质标本观察
【日期时间】自行替换
【地点】自行替换
【主色调】如：苔绿、烟紫灰、靛蓝、赤陶红

生成一张 9:16 竖版编辑感海报，整体为高级、克制、优雅的平面设计风格。暖象牙白纸张背景，带轻微天然纸纹与旧式印刷质感。画面采用明显的点线面构成：以 1 个完整的大圆形主视觉为核心，搭配 4–6 个大小不同的圆形、圆环或局部切面的几何元素，形成自上而下的非对称纵向结构。圆面内部加入与主题相关的细密纹理，如水纹、岩层纹、釉裂纹、香气扩散纹、植物肌理等，但整体保持二维平面感，不做 3D，不做摄影拼贴，不要电商感。

加入少量极细的纵向线、弧线或测量线，作为连接与节奏元素。下方或中下部放置 1 个小尺寸具象主体，作为视觉落点，例如器物、花枝、小型装置、标本、人物剪影等，主体不能过大，不能抢走几何构成的主导地位。

右侧安排大号纵向中文标题【标题】，字体修长、疏朗、留白充足；左侧或中下区域安排极细小字信息，包括【副标题】、【活动信息】、【日期时间】、【地点】与少量英文信息，形成“大字极疏、小字极密”的编辑反差。整体留白充分，信息密度克制，版式要像独立出版物或展览海报，而不是模板图。

色彩使用低饱和配色，以【主色调】为核心，可搭配 2–4 种辅助色，颜色要有层级但不过分花哨。整体气质安静、文艺、带日式编辑感与作品感。不要编号、不要水印、不要 Logo、不要版权字、不要 sparkle、不要四角星芒。

特别要求：顶部主圆必须完整显示，不能被左侧或顶部裁切；背景必须完整铺满整个画布，右侧不能出现额外白边或独立白栏；画面要像完整作品，不像占位模板。
