彩排路演的创始人，身后是一块空幕布

Picture a fictional adult Chinese-American founder, a man in his thirties with short black hair and a plain crewneck sweater, caught during a pitch rehearsal as a head-and-shoulders portrait. He stands mid-sentence, one hand open toward an empty projector screen on a plain wall, a half-smile of concentration on his face. He is fully clothed in modern business-casual wear, with natural, realistic features and a dignified, confident expression, in a plain contemporary setting with no readable text, logos, slides, signs or name badges. Render him as a minimal stippled poster print on warm cream paper, in a tall 9:16 portrait frame composed vertically. Every part of him, face, sweater and hand, is made of dense rust and sepia stipple dots that scatter into fine speckle at the edges. Behind the figure, soft overlapping translucent discs in apricot, coral and ochre glow like a low sun. The empty screen is only a pale rectangle, and a thin rule balances the poster layout. Colour and light: just two values, terracotta marks on pale sand paper. Light is flat and even, so stipple density carries all the tonal work. Keep the spacing calm and airy with wide sand-coloured margins. Mood: calm, focused, minimal.
