Generate a "central axis clamped" poster with strong visual impact and a high-end cultural exhibition temperament.

First, establish a clear and stable vertical central axis, then let the [Left Main Subject] and [Right Main Subject] jointly create visual weight from both sides of the frame, pushing the main title, characters, plants, or negative space areas towards the center.

The left and right subjects must be large enough, close to the edges of the frame, and allow for natural cropping, jointly bearing the primary visual weight. The two sides can differ in silhouette, size, color, material, and detail, but the overall visual weight must be balanced, avoiding simple duplication and mechanical mirroring.

Choose different clamping methods based on the theme:

Circular or arched subjects can use silhouettes to jointly clamp a central negative shape;
Architectural or screen spatial subjects can form depth in the central axis through perspective;
Flexible materials like fabrics or plants can form flexible clamping through natural bending;
Objects, characters, or cultural relics can strengthen the central title through left and right weighting.

The central axis must become the most important reading area of the frame. The Chinese main title uses a bold large font size, which can adopt vertical layout, mixed horizontal and vertical layout, scale changes, partial occlusion, or slight intersection with the subjects, letting Typography truly participate in the composition rather than being simply placed at the top.

Allow the central axis to include a low-weight visual node, such as a tiny character, flower branch, pattern rubbing, structural line drawing, or research diagram, giving the center both a focus and layering, but do not form a third subject of the same level.

Information density can be rich, but concentrated in 2–3 areas: the central axis core information, left and right sidebars, and bottom exhibition info. Form a clear font size contrast through oversized titles and tiny text; do not scatter small text evenly across the entire frame.

Use one clear large-area main color to establish recognition, such as cinnabar red, cobalt blue, lemon yellow, grass green, cyan blue, dark brown, or persimmon orange. Control the overall palette to 3–5 main colors, creating contrast through subject materials, Typography, and a very small amount of accent colors.

Core principle: It's not simple "bilateral symmetry," but using visual weight on both sides to jointly shape the center. The left and right are responsible for applying pressure, while the central axis is responsible for focusing; the structure is stable, but details allow for differences.

Overall requirements: Strong central axis, strong subjects, strong color gamut, clear sense of design, rich information but not chaotic, clear edges, distinct text, realistic materials, with the completion level of a mature cultural exhibition poster and Editorial Design.

生成一张具有强视觉冲击和高级文化展览气质的「中轴夹景」海报。

先建立一条明确、稳定的垂直中轴，再让【左侧主体】与【右侧主体】从画面两侧共同形成视觉重量，把主标题、人物、植物或留白区域推向中央。

左右主体必须足够大，靠近画面边缘并允许自然裁切，共同承担主要视觉重量。两侧可以在轮廓、大小、颜色、材质和细节上不同，但整体视觉重量必须平衡，避免简单复制和机械镜像。

根据主题选择不同的夹景方式：

圆形、弧形主体可利用轮廓共同夹出中央负形；
建筑、屏风等空间主体可通过透视形成纵深中轴；
织物、植物等柔性材料可通过自然弯曲形成柔性夹景；
器物、人物或文物可通过左右配重强化中央标题。

中轴必须成为画面最重要的阅读区域。中文主标题使用大胆的大字号，可采用纵排、横竖混排、尺度变化、局部遮挡或与主体轻微穿插，让 Typography 真正参与构图，而不是普通放在顶部。

允许中轴加入一个低权重视觉节点，例如极小人物、花枝、纹样拓片、结构线稿或研究图，让中央既有焦点又有层次，但不要形成第三个同等级主体。

信息密度可以丰富，但集中在 2–3 个区域：中轴核心信息、左右边栏、底部展讯。通过超大标题与极小文字形成明显字号反差，不要把小字平均撒满整个画面。

使用一个明确的大面积主色建立识别度，例如朱红、钴蓝、柠檬黄、草绿、青蓝、深棕或柿子橙。整体控制在 3–5 个主要颜色，通过主体材质、Typography 和极少量点缀色形成对比。

核心原则：不是简单“左右对称”，而是利用两侧视觉重量共同塑造中心。左右负责施压，中轴负责聚焦；结构稳定，但细节允许不同。

整体要求：强中轴、强主体、强色域，设计感明确，信息丰富但不乱，边缘清晰，文字清楚，材质真实，具有成熟文化展览海报与 Editorial Design 的完成度。
