a dynamic frontier beacon scene transmitting an evacuation signal during a sandstorm: has a guard light the second beacon against crosswind and signal an evacuation direction through sand with a shutter

Produce the main image for a local history exhibition to publication standard. Use 3:2; guide the eye through a 3:2 environmental narrative with hands and essential tools readable in the middle plane and the setting explaining the institution toward the tool exchange and hand action. Enter an earthen frontier beacon as a sandstorm approaches and show only a dynamic frontier beacon scene transmitting an evacuation signal during a sandstorm as the subject has a guard light the second beacon against crosswind and signal an evacuation direction through sand with a shutter. Use only this color-light system: tidal blue gray, sea-salt white, reed gold, and one rescue orange accent; light comes only from daylight, oil lamps, or braziers, keeping tools and clothing matte and period-consistent. Emphasize only this surface behavior: earth, stone, and ceramic retain grain, chips, and locally polished wear. Use fine colored line on paper with mineral pigments, keeping tools, clothing, and architecture within one coherent period logic; the clearest technical requirement is coherent period tools, clothing, labor gestures, and human relationships. Arrange the action layers as follows: Keep the full action “has a guard light the second beacon against crosswind and signal an evacuation direction through sand with a shutter” in one continuous plane, with its contact point and result both visible. The readable chain is “a dynamic frontier beacon scene transmitting an” to “has a guard light the second beacon against crosswind” to “has a guard light the second beacon against crosswind,” all grounded in “an earthen frontier beacon as a sandstorm approaches”. Final check: Do not show cinematic armor, modern objects, mixed periods, public-figure likenesses, or watermarks. Final art direction: museum-grade historical gouache and fine ink line with coherent period material culture. Use only this controlled palette: #4B3B32, #C2A56D, #27384B, #B64A38; preserve believable local material color inside that system. Keep one unmistakable primary subject and one readable action. The eye must enter at the action contact point, then read the consequence and finally the setting. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Human hands must be complete and anatomically plausible. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No visible text, letters, numerals, logos, brand marks, signatures, interface elements, labels, captions, borders, or watermarks anywhere in the image. Avoid plastic gloss, waxy skin, generic luxury-ad lighting, excessive bloom, meaningless lens flare, floating objects, duplicated limbs, clutter, random decorative icons, and synthetic AI collage artifacts. Return exactly one finished image composed for 3:2; no variants, process sheet, split panels, mockup frame, or contact sheet.

成片用途：地方历史专题展主画面。构图按3:2 环境叙事构图，手部和关键器物在中景清楚可读，背景交代制度与场所执行，成片比例 3:2。人物或对象是边塞烽燧在沙暴中传递撤离信号的动态场面，工作地点为沙暴逼近的土筑边塞烽燧，核心动作是守卒顶着横风点燃第二炬，并用遮板把撤离方向传给沙幕后的村落。现场光色按潮汐灰蓝、海盐白、芦苇金和一点救生橙；光线只来自天光、油灯或火盆，器物与服饰保持哑光和同一时代质感处理。动作相关材质：土石陶表面保留颗粒、缺口和局部磨亮处。采用纸本细线设色与矿物颜料，器物、服饰、建筑遵循同一时代逻辑；一致的时代器物、服饰、劳动动作和人物关系必须清楚可信。镜头动作说明：动作分层：前景清楚呈现「守卒顶着横风点燃第二炬」，中景以「并用遮板把撤离方向传给沙幕后的村落」交代结果，两层之间不插入其他事件。看清「边塞烽燧在沙暴中传递撤离」「守卒顶着横风点燃第二炬」与「并用遮板把撤离方向传给沙幕后」；场所仍为「沙暴逼近的土筑边塞烽燧」，不用摄影棚或抽象背景。画面文字按画面完全无字，不出现数字、品牌、签名或水印执行。不出现影视盔甲、现代器物、朝代混搭、公众人物脸或水印。
