古代女天文工匠校刻浑仪刻度的人物器物志：一手扶稳铜环、一手用细刻针修正刻度

按可发布标准完成历史教育专题图版。人物或对象是古代女天文工匠校刻浑仪刻度的人物器物志，工作地点为古代都城外的天文仪器作坊，核心动作是一手扶稳铜环、一手用细刻针修正刻度，旁边学徒核对星图与误差签。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。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。整体只使用这一组光色：雨云紫灰、湿石青、粉笔白和柿子橙；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。核心物件质感按器物尺寸、握持方式和服饰结构符合所处时代处理。镜头动作说明：动作分层：前景清楚呈现「一手扶稳铜环、一手用细刻针修正刻度」，中景以「旁边学徒核对星图与误差签」交代结果，两层之间不插入其他事件。让「古代女天文工匠校刻浑仪刻」的「一手扶稳铜环、一手用细刻针修」直接导向「旁边学徒核对星图与误差签」；背景只解释「古代都城外的天文仪器作坊」。画面文字按器物志只标「铜环、游标、刻针、星图」四项，标题为「测天之工」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。

The deliverable is a historical education plate. Enter an astronomical-instrument workshop outside an ancient capital and show only a figure-and-instrument atlas of an ancient female artisan calibrating an armillary sphere as the subject steadies a bronze ring with one hand and corrects its scale with a fine burin while an apprentice checks a star chart and error slip. Set the ratio to 3:2 and organize the camera through a 3:2 environmental narrative with hands and essential tools readable in the middle plane and the setting explaining the institution. Choose fine colored line on paper with mineral pigments, keeping tools, clothing, and architecture within one coherent period logic, and evaluate the result through coherent period tools, clothing, labor gestures, and human relationships. Use this lighting and palette: rain-cloud violet gray, wet-stone cyan, chalk white, and persimmon orange; light comes only from daylight, oil lamps, or braziers, keeping tools and clothing matte and period-consistent. Treat the main working objects as follows: tool scale, handling, and garment construction must fit the period. Arrange the action layers as follows: Stage the action in two layers: show “steadies a bronze ring with one hand and corrects its scale with a fine burin” clearly in the foreground, then use “an apprentice checks a star chart and error slip” in the middle plane as the consequence, with no unrelated event between them. Keep “an astronomical-instrument workshop outside an ancient capital” concrete while “a figure-and-instrument atlas of an ancient female” completes “steadies a bronze ring with one hand and corrects” and resolves “an apprentice checks a star chart and error slip”. 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.
