海岸线清扫日

制作「海岸线清扫日」活动海报，采用 3:4 画布，面向普通社区参与者。核心关系是“垃圾夹与手套交叉成海岸坐标轴”。从支点、重量和阴影建立因果，拒绝漂浮拼贴，使“垃圾夹与手套交叉成海岸坐标轴”保有可信的物理关系。主视觉和排版共同服从偏心竖构图，不要把文字贴在图像之外。文字区域逐字呈现「海岸线清扫日」「让公共空间拥有温度」「临河观察台」「穿防滑鞋并带铅笔」，不生成伪字或额外口号。辅物控制在真实比例标本、风向线和水汽三类以内；选择双色丝网印刷与矿物颜料薄层与深海蓝、壳白、海藻绿与柿橙，拒绝覆盖式旧化滤镜。接近地平线的晨光作为唯一主光，接触影较硬，远端影逐渐变软，所有投影方向一致。最终图像仅含招贴本身，裁切不碰关键信息；不借品牌、明星、IP、HUD、二维码或奢华展示获取注意，保持「海岸线清扫日」的公共活动语气。

Produce a 3:4 event poster for “Coastline Care Day,” aimed at ordinary community participants. The core relationship is litter tongs and work gloves crossing to create a coordinate axis for the coastline. Build causality through support, weight, and shadow rather than floating collage. Make image and typography share an asymmetric vertical composition; do not park text outside the artwork. Write “Coastline Care Day,” “Bring warmth to shared space,” “the riverside observation deck,” and “wear nonslip shoes and bring a pencil” accurately, with no pseudo-text or extra slogan. Keep supporting objects within true-scale specimens, wind-direction lines, and moisture. Combine two-color screen printing with thin mineral-pigment layers and deep-sea blue, shell white, seaweed green, and persimmon orange without an all-over aging filter. Use low morning light near the horizon as the only key light. Contact shadows are harder, distant shadows soften, and every projection shares one direction. Show only the placard, with essential information protected from trim. Use no brand, celebrity, IP, HUD, QR code, or luxury display shortcut. For the final rendering, use one carefully engineered physical illusion for the hero: litter tongs and work gloves crossing to create a coordinate axis for the coastline. Show enough thickness at the cut edge to establish the material, while the background remains flat and quiet. Keep the title’s baseline stable even where the hero approaches the letterforms. 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.
