"scene_type": "Chinese physics examination paper",
"gen_brief": "A finished Chinese university entrance examination practice paper, rendered as a crisp, straight-on scan of a single A4 sheet. The design follows formal examination typography, with restrained black ink, precise mathematical notation, generous writing margins, and finely drawn physics figures. The paper is clean white under even illumination, without photographic perspective or distracting surface texture. Dense but readable Chinese typesetting, differentiated heading weights, consistent option spacing, and carefully aligned question numbers create an authentic printed assessment. All questions remain unanswered, and the document clearly identifies itself as a practice examination.",
