Candid documentary-style UGC smartphone studio snapshot of a young woman seated on a blue-gray studio mat, torso leaning back supported by both arms extended behind with palms flat on the floor, legs bent at the knees with feet elegantly pointed, toes touching the floor, head turned over her shoulder into the camera with a calm gaze. Exactly two arms and two hands, anatomically connected, clean fingers and toes, no extra limbs. Cream sport crop top with periwinkle trim and color-block panels, high-waisted lime chartreuse shorts, medium-length dark wavy hair, glossy natural makeup. Pitch-black backdrop, white brand lettering partially visible on the floor. Hard directional spotlight, bright skin highlights, crisp floor shadow, deep black falloff, natural smartphone exposure. Vertical full-body seated framing, casual confident composition, slight grain, authentic activewear test-shoot snapshot character.
