Dark Chinese Industry Quote Poster

Goal: Create a vertical Chinese business keynote quote poster featuring a serious industry expert portrait and bold editorial typography. Canvas: 2:3 vertical poster, dark premium corporate style, black-to-charcoal vignette background with a soft gray halo behind the subject, high contrast, cinematic lighting. Main subject: One centered East Asian male expert, about 35–45 years old, short black hair, round black eyeglasses, calm serious expression, looking directly at the viewer. He wears a black suit or dark blazer. Pose him leaning forward with both hands clasped under his chin, elbows implied below frame. Use realistic studio portrait photography, sharp facial detail, moody side lighting, shallow depth of field. Layout: The portrait fills the upper two thirds of the poster. Place the text block over the lower half, aligned left, leaving the face unobstructed. Use a large white quotation mark at the lower left above the headline. Add a thin vertical red line along the left side of the main text block and small red accent lines. Text content: Include exactly 1 oversized white opening quotation mark. Include exactly 2 small labels above the headline: a red rectangular label with white Chinese text “行业观察”, followed by a small gray label “专栏”. Include exactly 1 large bold white Chinese headline: “当增长放缓，真正的竞争才开始”. Under it, include exactly 3 insight bullet lines, each with a small white icon and red accent: 1) “需求进入存量时代，增长逻辑全面重构” with an upward chart icon, 2) “从规模扩张转向效率提升，组织能力是关键” with a person icon, 3) “技术与场景深度结合，构建可持续的竞争壁垒” with a target icon. At the bottom left, include exactly 1 author block: “张睿 资深行业分析师” and below it “专注产业研究与企业战略”. Typography and style: Heavy condensed sans-serif Chinese headline, bright white text with subtle shadow, clean smaller gray body text, red accents in a vivid corporate red. Overall mood should feel like a high-end conference speaker poster, business magazine cover, leadership profile, or industry commentary card. Customizable fields: Use speaker_name, speaker_title, headline_text, category_label, and subtitle_label. Constraints: Keep the poster dark, minimalist, and premium. Do not add logos, watermarks, QR codes, extra people, extra bullet points, or extra decorative elements. Ensure all Chinese text is legible and correctly placed.
