Manifesto editoriale per mostra culturale con composizione diagonale

Design a 9:16 vertical cultural exhibition poster with an overall contemporary Editorial Graphic Design / art-publication aesthetic. 【Theme】：____ 【Chinese title】：____ 【English title】：____ 【Main visual】：____ 【Auxiliary pattern】：____ 【Primary color】：____ 【Secondary color】：____ 【Date / Institution】：____ At the core, use a "diagonal potential" composition, but do not draw obvious diagonal lines. First establish a hidden diagonal visual axis, letting the visual weight of the main visual, Chinese title, pattern, date information, and negative space progress gradually in the same direction. The main visual carries the primary weight; the large Chinese title must participate in the layout, and may be offset, set vertically, partially cropped, or lightly interwoven with the subject; the English title, date, and institution information are shrunk and concentrated in 2–3 areas, forming a clear type-size hierarchy. Each piece uses only one auxiliary pattern language, related to the theme itself — for example a sound print, map folding, object rubbing, or botanical rubbing. Do not add multiple sets of decorative elements just for richness. The background must also participate in the design: use art-paper texture, very faint pattern residue, technical drawings, specimen information, or material textures, giving the negative space layers while staying clear from a distance. The information density is medium-high, but there must be hierarchy: first glance — the composition and subject; second glance — the Chinese title and pattern; third glance — the English, date, and auxiliary information. Keep the color to 3–4 main colors, creating tension through scale, cropping, overlap, density, and negative space. Overall effect: a cultural exhibition poster, editorial design, the feel of a mature print publication, rich but not messy, with diagonal potential present naturally — do not arrange elements just to look "diagonal." 4 replaceable cases: 1.
