  "prompt": "A candid 3:4 portrait of [an East Asian girl with a K-pop idol aesthetic] taking a brief break on a bench in an empty rehearsal hallway outside a practice room door. Shot from a slightly low seat-level perspective where the hallway vanishing lines, practical fluorescent lights, and bench edge naturally frame her. She has a shy-but-aware expression, clear eyes, and a defined waist silhouette. Natural posture, believable fabric weight, subtle skin texture, and realistic smartphone candid aesthetic with restrained contrast.",
