Reference frame, scene 3. Vertical 9:16. Pixar-style realistic 3D,
school biology classroom, anatomy posters, daylight, film grain.
Composition: Alisa_master @image1 standing confidently by the board addressing
the class, braces, mouth in frame; Sonya_master at a desk, arms
crossed, smug-but-wary, mouth in frame; other students in soft focus
turned to listen. Camera: medium. Key visibility: Alisa commanding the
room + Sonya's wariness readable, mouths in frame. Negative: no on-
screen text, no logos, no flat cartoon, no anime, no blurred faces.
