用肥皂泡折射星图的阳台天文学家：把一张星图弯进大泡泡表面

交付目标是自然教育工作坊主题插画。主体为用肥皂泡折射星图的阳台天文学家，位于停电阳台上的临时观星台，正在把一张星图弯进大泡泡表面，等待远处窗灯与星位重合。整体只使用这一组光色：砂岩色、烟青、松针绿和琥珀高光；亮暗由所选手工媒介的叠层和留白形成，不使用塑料高光或摄影光斑。比例定为 4:5，视线通过4:5 单幅叙事构图，动作点位于下方三分线，周围留出媒介纹理的呼吸区抵达动作轮廓与媒介边缘。画面语言为水粉、蜡笔与撕边手工纸混合，刷痕和纸纤维真实可见，重点是纸纤维、手撕边缘、叠层阴影和留白关系。物件表面只强调主体边缘保留手工媒介痕迹，动作接触处清楚，不增加无关装饰。动作阅读顺序：动作分层：前景清楚呈现「把一张星图弯进大泡泡表面」，中景以「等待远处窗灯与星位重合」交代结果，两层之间不插入其他事件。让「用肥皂泡折射星图的阳台天」的「把一张星图弯进大泡泡表面」直接导向「等待远处窗灯与星位重合」；背景只解释「停电阳台上的临时观星台」。文字仅按画面完全无字，不出现数字、品牌、签名或水印处理。角色必须原创，避免僵硬肢体、漂浮物件、过饱和霓虹和 AI 水印。

Create one finished 4:5 image in original handmade mixed-media illustration. Finished use: a feature illustration for a nature-education workshop. The central event is a balcony astronomer refracting star charts through soap bubbles at a temporary balcony observatory during a blackout, where the subject curves a star chart over a large bubble and waits for distant windows to align with stars. Keep the scene concrete and the primary action unmistakable; use a clear foreground action, one consequence, and a restrained environment. Use only this controlled palette: #D8C18E, #657A52, #6D6A63, #E6A07A; keep one believable light direction and physical material detail. No visible text, letters, numerals, labels, logos, brands, signatures, interface elements, borders, or watermarks. No public figures, copyrighted characters, duplicated limbs, floating objects, plastic gloss, or synthetic collage artifacts. Return exactly one image at the requested 4:5 composition, using the heige-image 1K bucket; no variants or process sheet.
