Celtics-fans juichen in een NBA-arena.

Create a photorealistic vertical waist-up close-up of a {argument name="subject" default="young morena woman basketball fan"} sitting in the lower-bowl audience at a packed Boston Celtics NBA playoff game. She is centered close to the camera, wearing a green {argument name="jersey text" default="CELTICS"} basketball jersey with the number 0 and a black varsity jacket with glossy leather sleeves, green-and-white striped cuffs, silver snap buttons, and a round Celtics shamrock patch on the chest. She has long voluminous dark curly hair, small hoop earrings, and a radiant game-day makeup look; her face should be visible and expressive, showing an emotional cheering reaction. Pose her with one arm raised high in a clenched-fist celebration while the other arm is lower near the seat, as if reacting to an intense play. The background is a fully sharp, busy NBA arena interior with a basketball court visible below, dense cheering crowd, green Celtics playoff ribbon boards, bright stadium lights, and a large overhead jumbotron showing the live court and scoreboard details. Use realistic arena lighting, crisp detail throughout the packed stadium, natural skin texture, authentic sports-photo perspective, 35mm documentary photography feel, high dynamic range, no blur, no watermark, no extra logos beyond Celtics-style arena and jersey details.
