the SmartBlack_master black floss wound on her fingers, the black
strand visible against her teeth, braces, focused, mouth/hands in
frame, REVYLINE branding on the dispenser readable; Masha leaning in
curious in soft focus. Camera: tight close-up. Key visibility:
REVYLINE branding + black floss contrast sharp, flossing technique
clear, mouth in frame. Negative: no on-screen text, no logos other
