白描

保持用户指定的主体、数量、动作、场景、身份与叙事关系不变；用户明确指定的构图、镜头、画幅与文字内容优先；不新增主体、人物、道具、纹样或叙事元素。以白描作为主导视觉方向。构图：使用开放留白和清晰轮廓层级，减少背景信息，使用户主体与关键动作成为唯一视觉重点。造型：严格保留主体数量、身份、结构和动作，仅用不同线宽、浓淡与转折表现外轮廓、内部结构和体积。色彩：墨黑、淡墨与纸白为主，可使用极少朱砂印记；不使用大面积彩色填充。光影：不依赖写实光影，体积主要由线条疏密、转折与重叠关系表达。材质：细毫毛笔、宣纸或绢本，保留轻微墨线渗化和干湿变化。文字控制：仅在用户要求文字时使用与线描一致的细雅书写，不添加无关题款。主体边界：不改变用户主体解剖、轮廓和数量，不新增装饰背景；视觉变化必须由线条系统完成。

Preserve the user-defined subjects, count, actions, setting, identities, and narrative relationships. User-specified composition, camera, aspect ratio, and exact text take priority. Do not add subjects, people, props, motifs, or story elements. Use Baimiao Line Drawing as the dominant visual direction. Required execution details: open negative space with a clear contour hierarchy, continuous ink lines with controlled width, density, and turning rhythm, monochrome relationships among black ink, pale ink, and paper white, volume expressed through line density without realistic cast shadows, fine brushwork, paper fiber, and subtle ink bleeding, delicate writing consistent with the line system only when requested. Apply typography only when the user requests text and preserve the exact wording.
