山城楼梯赛

生成一张「山城楼梯赛」海报，画幅 4:5，用于一场小型公共文化活动。画面中心呈现“山城阶梯折成竖直心电图”，物件要真的接触并产生形变，不增加第二个视觉噱头。整体依照偏心竖构图组织，留白只用于强化核心隐喻，让“山城阶梯折成竖直心电图”保持第一视觉中心。请准确排出「山城楼梯赛」与「慢一点，细节才会出现」，并在信息区写明「旧水厂北厅」「提前十分钟签到」。辅物控制在导向箭头、手写纸条和材料样本三类以内；选择木刻线条与暖白棉纸与靛青、竹青、旧纸白与朱砂，拒绝覆盖式旧化滤镜。照明设为低位工作灯，高光与纸面漫反射分别可信，不做舞台泛光。成片在纸张裁切处结束，所有小字清楚。省略二维码、商业标识、既有角色、旅游拼贴、HUD 和无物理来源的霓虹，保持「山城楼梯赛」的公共活动语气。

Create a “Stair City Challenge” poster in a 4:5 frame for a small public culture event. Center the image on a mountain-city staircase folding into a vertical electrocardiogram. The objects physically touch and deform, with no second visual gimmick. Organize the artwork through an asymmetric vertical composition, using negative space only to strengthen the metaphor. Typeset “Stair City Challenge” and “Slow down and the details will appear” accurately, then state “the north hall of the former waterworks” and “check in ten minutes early” in the information region. Keep supporting objects within directional arrows, handwritten slips, and material samples. Combine woodcut linework on warm cotton paper and indigo, bamboo green, aged-paper white, and vermilion without an all-over aging filter. Set illumination to a low work lamp, separating believable highlights from paper diffusion and avoiding theatrical bloom. End at the paper trim with clear small copy. Omit QR codes, commercial marks, existing characters, travel montage, HUD graphics, and unjustified neon. For the final rendering, turn the concept into a single stable studio arrangement: a mountain-city staircase folding into a vertical electrocardiogram. Keep the object fully inside the trim and let negative space separate the metaphor from the event information. Preserve clean counters in the headline and prevent texture from entering the small type. 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 4:5; no variants, process sheet, split panels, mockup frame, or contact sheet.
