Windowsill Seed Bank

Output a finished 3:4 “Windowsill Seed Bank” poster for a realistically small event. Center the image on window-box planters indexed by the year their seeds were collected. The objects physically touch and deform, with no second visual gimmick. Use an asymmetric vertical composition; the hero is the first focal point, followed by title and event copy. Read “Windowsill Seed Bank” first, followed by “Leave one observation for the next visitor” and “the riverside observation deck / wear nonslip shoes and bring a pencil.” Use no malformed characters. Introduce no decoration beyond true-scale specimens, wind-direction lines, and moisture. Construct the print in two-color screen printing with thin mineral-pigment layers, with visible pressure and ink change, colored through rust red, platform gray, rice beige, and peacock blue. Set illumination to low morning light near the horizon, separating believable highlights from paper diffusion and avoiding theatrical bloom. Keep headline, secondary line, and venue within trim safety. Remove mockups, sponsor logos, public figures, character assets, and excess lighting. For the final rendering, treat the metaphor as a small constructed still life: window-box planters indexed by the year their seeds were collected. Retain small traces of handling, such as pressure, fiber lift, or abrasion, only where the object would actually be touched. Make the venue and participation note readable at arm’s length in the finished print. Final art direction: editorial poster design with a disciplined grid and material-aware composition. Use this controlled palette as the dominant visual system: #F2EBDD, #243447, #C65D48, #D6A14B; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 3:4; no variants, process sheet, split panels, mockup frame, or contact sheet.

输出「窗台种子银行」海报成片，画幅 3:4，对应真实可举办的小型活动。画面中心呈现“窗台花盆按种子年份编号”，物件要真的接触并产生形变，不增加第二个视觉噱头。构图采用偏心竖构图，主物是第一视点，标题与活动小字沿随后动线展开，并为「窗台种子银行」的活动信息留足空间。主字「窗台种子银行」先被读到，随后是「把一次观察留给下一位来者」和「临河观察台／穿防滑鞋并带铅笔」，不可出现乱码。除真实比例标本、风向线和水汽外不添加装饰。材料按双色丝网印刷与矿物颜料薄层制作，纸面受压与墨色变化清楚，使用铁锈红、站台灰、米黄与孔雀蓝。照明设为接近地平线的晨光，高光与纸面漫反射分别可信，不做舞台泛光。把标题、副句和地点放在安全边内。去掉样机、赞助 Logo、公众人物、角色资产和多余光效，保持「窗台种子银行」的公共活动语气。
