退潮时出现的邮局叙事关键帧

制作一张高完成度的「退潮时出现的邮局」，核心任务为退潮海床上出现一间只营业两小时的临时邮局。
一体化呈现退潮海床上出现一间只营业两小时的临时邮局；中景安排相互依赖的动作，远景只交代这件事需要的天气、距离、地点或时间压力
定格退潮海床上出现一间只营业两小时的临时邮局即将改变局势的一秒，关键物件进入前景，普通人的手势、重心和视线连成可读因果
「退潮时出现的邮局」只安排二至五名与退潮海床上出现一间只营业两小时的临时邮局明确地有关的人物，操作停在仍有悬念但已能判断下一步的瞬间；道具必须在这场事件中被拿起、递交、固定、阅读或使用。
构图采用中心剖面加四角细节。
唯一醒目文案为「退潮时出现的邮局」，局部标注维持短、准、可对应。
「退潮时出现的邮局」采用均匀漫射顶光，从操作点向落点区自然移焦；各个衣料、道具和环境表面都服从退潮海床上出现一间只营业两小时的临时邮局发生时的天气、重量和接触关系。文字选择标题靠近主视觉、注释贴近对应对象，背景为保留少量使用痕迹的工作台，整体完成为克制的电影核心帧质感。补充控制：层次清晰的浅灰投影，软质部分自然卷曲、硬质部分确保受力；以冷暖差区分主体和环境，主视觉清晰，注释区确保同等可读，局部亮色只用于操作方向。
排除无因爆炸、夸张哭喊、断裂视线、跨项目道具、空洞奇观与不符合现场时间的光源，不加入跨领域道具、账号、水印或难以执行的抽象口号，用于「退潮时出现的邮局」。
成片为单张 4:5，不附过程页或变体。

Create one 4:5 image of The Post Office Revealed by Low Tide. Depict a temporary post office exposed on the seabed and open for only two hours as one continuous event. Situate interdependent actions in the middle distance, and reserve the background for only the weather, location, travel distance, or time pressure required by this story for The Post Office Revealed by Low Tide. Freeze the second in which a temporary post office exposed on the seabed and open for only two hours is about to change the situation; bring the decisive object forward and connect ordinary people via gesture, balance, and eye line. Limit The Post Office Revealed by Low Tide to two to five people directly involved in a temporary post office exposed on the seabed and open for only two hours, pausing them at a tense instant from which the next step remains inferable. Each prop in this event must be held, passed, secured, read, or used instead of merely decorating the scene. Use the specified 4:5 layout. Use “退潮时出现的邮局” as the sole prominent line, keeping local annotations brief, accurate, and connected. Use night blue, luminous cyan, lime green, and silver gray together with natural highlights and contact shadows that prove the scale and weight of only objects and environmental surfaces that naturally belong to a temporary post office exposed on the seabed and open for only two hours. Give The Post Office Revealed by Low Tide even diffused overhead light and focus moving naturally from the operation to the finished state; make clothing, props, and environmental surfaces obey the weather, weight, and contact conditions of a temporary post office exposed on the seabed and open for only two hours. Choose headline near the hero and notes beside their objects over a work surface using limited use marks, completing the image using a restrained cinematic-key-finished picture finish. Additional control: clearly layered pale-gray shadows; soft parts bend naturally while rigid parts carry load. Use warm-cool separation between subject and setting, ensure hero and annotation zones remain equally legible, and let the local bright hue indicate operation direction only. Exclude causeless explosions, melodramatic shouting, broken eye lines, cross-project props, empty spectacle, or lighting inconsistent with the event time, adding no cross-domain prop, source handle, watermark, or abstract slogan that cannot be depicted for The Post Office Revealed by Low Tide. Return one 4:5 final image without variants or a process sheet. Final art direction: cinematic narrative still with realistic blocking and one decisive story beat. Use this controlled palette as the dominant visual system: #172B3A, #6F8C8D, #D2B46C, #D65F43; preserve believable local material colors within it. Keep any text absent or minimal unless the source brief explicitly requires it; never add logos, signatures, 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.
