Social Media Post - Modern Staircase Group Portrait

Create a photorealistic, high-detail lifestyle photograph of three young women posing together on a modern wooden staircase inside a stylish contemporary home. Do not reference or resemble any real celebrity or public figure.\n\n1. Subjects, hair, skin, expressions & poses:\n\nWoman on the left: young woman with fair skin, light blonde hair styled in a neat high ponytail with a few soft strands framing her face. She has natural facial features, subtle makeup, and a relaxed, friendly expression. She sits comfortably on a wooden stair with one arm raised casually toward her hair, looking toward the camera with a confident but natural smile.\n\nWoman in the center: young woman with fair skin and blonde hair pulled into a sleek ponytail. She has softly defined eyebrows, natural makeup, and a calm, composed expression while looking slightly toward the side. She stands or sits one step higher than the others, creating a layered composition.\n\nWoman on the right: young woman with fair skin and long copper-red hair gathered into a ponytail, with a few loose strands around her face. She has subtle freckles, natural makeup, and a relaxed expression. She sits sideways on a lower stair with one hand resting naturally on the step while looking toward the camera.\n\nKeep all three women anatomically natural and proportionate, with realistic hands, facial symmetry, hair strands, and natural posture.\n\nTheir interaction should feel like a casual group photograph between friends.\n\n2. Clothing & accessories:\n\nLeft woman wears a green-and-black horizontally striped sleeveless summer dress with a simple elegant design, paired with a delicate gold necklace and small earrings.\n\nCenter woman wears a navy-and-blue striped sleeveless dress with a clean contemporary design and minimal jewelry.\n\nRight woman wears a burgundy-and-black striped sleeveless dress, with subtle jewelry and visible decorative tattoo artwork on her upper arm.\n\nUse realistic fabric texture, stitching, folds, and natural draping.\n\nKeep the styling fashionable but tasteful and suitable for a casual lifestyle photograph.\n\n3. Environment & lighting:\n\nSet the scene inside a bright, {argument name="setting" default="modern multi-level home with a distinctive wooden staircase"}, white structural beams, thin metal cable railings, and warm wooden steps.\n\nInclude contemporary architectural details, glass panels, neutral walls, minimalist furniture, and subtle decorative elements in the background.\n\nLarge windows allow soft daylight to enter the room.\n\nUse warm ambient interior illumination combined with natural daylight for a welcoming atmosphere.\n\nCreate realistic shadows and gentle highlights across the subjects and staircase without excessive contrast.
