Museum Poster Design Template Prompt

Generate a quiet and ceremonial graphic visual centered around {argument name="subject" default="any subject object"}: the frame forms a strong column order with a large theme background and a centered narrow main visual strip. The main visual strip carries the main forms, linear textures, or image narratives derived from the theme, running through the reading path like a precisely framed fine image; the two background fields remain wide, soft, and breathable, with a small number of theme-related artifacts or symbols placed as lightweight anchors, so the eye first reads the dense details in the center, then the large headings and grouped information. The theme object should not be displayed in isolation, but disassembled into four roles: main form, attached details, information layers, and small objects, forming an exhibition rhythm of dense center, sparse sides, and paused text. If text appears, use tall, thin, elegant title characters with letter spacing, forming silent weight in few-word columns; descriptive text uses small, neat, restrained blocks, maintaining precise margins with images, like exhibition labels and date information embedded in the color field. Colors are extracted from the theme's own material, season, cultural semantics, and emotions, retaining the role relationships of a large clear and bright base color, a lighter main visual support color, clear light and dark gradations, a small amount of high-saturation emphasis color, and light-colored information text; overall bright and clean, warm and quiet, with clear boundaries and soft printing grains, texture only increases paper and material tactile feel, without making the image dirty, dim, smoky, or old.
