Photorealistic vertical 9:16 phone-video frame. The same original young American woman (about 30, chestnut-brown wavy shoulder-length hair, warm friendly face, heather-grey scoop-neck t-shirt), soft neutral warm wood-panel wall background, natural soft light.
Chest-up, slightly tilted head. She slides two flat fingers DOWN the side of her neck, from below the ear toward the collarbone, demonstrating a lymphatic drainage stroke, looking toward the camera. The downward sliding motion is clear. Natural realism. No on-screen text, no captions, no watermark.
