Reference frame, scene 4. Vertical 9:16. Pixar-style realistic 3D,
classroom, daylight, film grain. Composition: three-shot. LEFT — a
generic teacher (50, glasses, cardigan) holding a gradebook, impressed
at Alisa, then sharp at Sonya, mouth in frame. CENTER — Alisa_master,
quietly triumphant, braces, mouth in frame. RIGHT — Sonya_master
caught, the USB visible, shrinking, mouth in frame. Camera: medium
three-shot. Key visibility: teacher's verdict + Alisa's win + Sonya's
exposure readable, mouths in frame. Negative: no on-screen text, no
logos, no flat cartoon, no anime, no blurred faces.
