生成一张「(主题/剧情一句话描述)」的二维扁平叙事插画，整体为 Flash/MG 动画分镜截图风：干净矢量描边（外轮廓略粗、线条利落），大色块平涂为主，阴影仅用少量柔和渐变，不做复杂材质与写实纹理；场景为(地点/时代/环境)的中远景分镜构图，主体是(人物/物体)正在(动作/状态)，表情清晰可读但五官简化；色彩低饱和偏灰暗，氛围(悬疑/压抑/温暖/荒诞)，画面带轻微暗角与聚光，背景概括化不抢主体；底部保留一行简体中文字幕「(字幕内容)」，画幅(16:9/9:16/4:3)，高清输出。
Generate a 2D flat narrative illustration of 「(主题/剧情一句话描述)」, overall style mimicking a Flash/MG storyboard screenshot: clean vector strokes (slightly thicker outer contour, crisp lines), large flat color blocks, only a few soft gradients for shadows, no complex materials or realistic textures; the scene is a medium-to-long shot set in (地点/时代/环境), the main subject is (人物/物体) in the act of (动作/状态), facial expression clear but features simplified; colors low-saturation and slightly gray, atmosphere (悬疑/压抑/温暖/荒诞), slight vignette and spotlight, background generalized so it doesn’t steal focus; a line of Simplified Chinese subtitle 「(字幕内容)」 is kept at the bottom, aspect ratio (16:9/9:16/4:3), HD output.
