Fashion Editorial: Woman on Arcade Stairs

Photorealistic fashion editorial photo of {argument name="subject" default="a clearly adult woman in her twenties"}. Pose lock: {argument name="pose" default="wide low stair sit"}. She sits low across two or three shallow steps, with one knee raised and the other leg extended diagonally down the stairs. Hips angled sideways, torso leaning forward but lifted, shoulders uneven. One hand is planted behind or beside her on the step for structure, the other arm rests across the raised knee or thigh. Direct eye contact, calm and magnetic. The pose should be low, strong, and graphic, not cute stair sitting. Background identity: {argument name="background" default="a colorful underground game-center stair passage with red-blue-yellow painted steps, fictional anime arcade posters, rhythm game flyers, capsule toy ads, sticker layers, neon arrows, glowing floor strips, checkerboard wall tiles, reflective metal railings, and dense pop signage"}. The space should feel like a secret entrance to a Japanese arcade and anime shop. Composition lock: tight vertical 4:5 crop from low stair angle. Stair diagonals, raised knee, torso, poster-covered walls, and neon arrows create the image. Subject large in frame. Avoid: anime style, illustration, plain stairwell, tourist stair photo, standing on stairs, soft sitting, real logos, readable text, posters blocking the body.
