金融从业者肖像

生成一张 4:5 竖版金融从业者肖像。中国女性投资研究员穿深蓝衬衫和黑色西装外套，坐在暗色交易研究室的多屏工作台前，手边有计算器、无字笔记本和一杯黑咖啡。屏幕上只能出现抽象折线、柱形和色块，不能有股票代码、数字、英文或中文。她侧身看向镜头，表情专注冷静。光线为屏幕冷光加桌面暖光，色调深蓝、炭黑、少量琥珀色，高级但不压暗。真实商业摄影，70mm 镜头，半身构图，人物比例真实。画面内不要出现任何可读文字、logo、水印、真实金融机构名、ticker 或品牌标识。

Create a 4:5 vertical finance professional portrait. A Chinese female investment researcher in a deep navy shirt and black blazer sits at a multi-monitor workstation in a dark trading research room, with a calculator, blank notebook, and black coffee nearby. The screens show only abstract line charts, bars, and color blocks, with no stock codes, numbers, English, or Chinese text. She turns slightly toward the camera with a focused, calm expression. Cool monitor light mixed with warm desk light; deep blue, charcoal, and small amber accents, premium but not underexposed. Real commercial photography, 70mm lens, half-body composition, realistic proportions. No readable text, logo, watermark, real financial institution name, ticker, or brand mark anywhere in the image.
