Photorealistic vertical 9:16 phone-video frame. An original young American woman, about 30, warm friendly face, clear healthy skin, shoulder-length wavy chestnut-brown hair, wearing a simple heather-grey scoop-neck t-shirt so her neck and collarbones are visible. Soft neutral warm wood-panel wall background (home setting), natural soft light.
Chest-up framing. She presses two fingertips into the small hollow just ABOVE her right collarbone and looks into the camera with a calm, demonstrating expression. The collarbone area and her pressing fingers are clearly visible and in focus. Natural phone-selfie realism. No on-screen text, no captions, no watermark.
