花粉季来信

以「花粉季来信」为主题完成 16:9 招贴，避免商业促销语气。把“花粉像邮戳落在透明纸上”按可制作的物理结构呈现，支撑、弯曲和投影依次发生。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「花粉季来信」的活动信息留足空间。请准确排出「花粉季来信」与「从街角练习共同生活」，并在信息区写明「临河观察台」「穿防滑鞋并带铅笔」。把真实比例标本、风向线和水汽作为主物证据；双色丝网印刷与矿物颜料薄层保留真实纹理，靛青、竹青、旧纸白与朱砂按主色、辅助色、强调色分配。只用阴天漫射天光塑造结构，禁止额外轮廓光或霓虹边缘，保持「花粉季来信」的公共活动语气。四边给文字留出安全距离，只输出可印海报本体，服务于「花粉季来信」的单一视觉命题；不出现墙面、手持展示、机器可读代码、名人或赛博界面，保持「花粉季来信」的公共活动语气。

Complete a 16:9 placard around “Letters from Pollen Season” without promotional sales language. Render pollen landing on translucent paper like postal cancellation marks as a buildable physical structure, with support, bending, and projection occurring in order. Use an asymmetric vertical composition; the hero is the first focal point, followed by title and event copy. Typeset “Letters from Pollen Season” and “Practice living together from the street corner” accurately, then state “the riverside observation deck” and “wear nonslip shoes and bring a pencil” in the information region. Treat true-scale specimens, wind-direction lines, and moisture as evidence for the hero. Preserve two-color screen printing with thin mineral-pigment layers texture and divide indigo, bamboo green, aged-paper white, and vermilion into dominant, supporting, and accent roles. Use only diffuse overcast daylight to reveal structure and add no rim glow or neon edge. Give copy safe distance from every edge and output the print itself. Include no wall, hand, machine-readable code, celebrity, or cyber interface. For the final rendering, make the central relationship clear before any decorative detail: pollen landing on translucent paper like postal cancellation marks. Make the connection mechanically plausible, with no floating pieces and no glow used to conceal a join. Use the quietest color for the longest text and reserve the accent for one measured point. 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 16:9; no variants, process sheet, split panels, mockup frame, or contact sheet.
