โปสเตอร์ตัวอักษรงานคีย์โน้ตสีม่วงสไตล์มินิมอล

Minimalist corporate keynote poster in a bold Chinese typography style, wide 16:9 horizontal format. Setting: Deep saturated purple background filling the entire frame, with subtle studio-floor shading, a faint vignette, and an empty right side providing dramatic negative space. Layout: All content arranged within the left third of the image. At the upper left, small gray uppercase text: "04 / ZHANG YIMING". Below it, an enormous blocky white Chinese headline reading "[算法]", set in an ultra-heavy geometric display font with tight tracking and slight horizontal cutouts. Beneath the headline, three small white profile lines: "[张一鸣]", "Entrepreneur / ByteDance", and "ByteDance". Behind and below the profile text, two very large low-opacity vertical English words, "ALGORITHM" and "BYTE", stacked and subtly fading into the purple background. Subject: An East Asian male entrepreneur, [Zhang Yiming], seated near the lower left-center below the headline. He wears all-black casual attire: a black hoodie or jacket, black shirt, black trousers, and black sneakers. He has short black hair, glasses, and a calm, contemplative expression, sitting on a dark minimalist cube stool with hands loosely clasped, body angled slightly right while looking upward to the right. A small framed tablet or plaque rests on the purple floor near his right foot showing a faint chart graphic. Lighting: Realistic photographic studio lighting with soft floor cast shadows and a subtle rim light separating him from the deep purple backdrop. Clean, high-contrast, cinematic aesthetic with no decorative borders or extra figures.
