咖啡馆肖像遮挡照片

Create a realistic candid portrait photograph of a young East Asian woman seated indoors in a cozy cafe or lounge, framed from chest up in a vertical 3:4 composition. She has {argument name="hair color" default="long straight black hair"} with soft natural shine, slightly tousled strands, and hair falling over both shoulders. She wears a loose {argument name="shirt color" default="white"} crewneck T-shirt with a colorful floral graphic on the chest. The background is softly blurred with warm ambient lighting, golden yellow wall tones on the left, neutral shelves in the upper right, and a brown leather or vinyl sofa behind her. Use shallow depth of field, natural indoor light, realistic skin and hair texture, DSLR portrait look, soft bokeh, casual intimate mood. Add a semi-transparent white watermark reading {argument name="watermark text" default="Alconia"} in the bottom-left corner.
