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.
