Casual vertical iPhone photo taken from the back of a bright modern school classroom in daytime. The same young woman as in the reference image (about 30, dark-blonde messy bun, thin black-framed glasses), now in a smart casual light blouse, confidently teaches next to a large interactive whiteboard whose content is softly out of focus and unreadable. Several 13-year-old students at desks raise their hands, engaged and smiling. Sunlight through big windows, natural phone-camera look, slight digital noise, imperfect handheld framing. Photorealistic. No readable text, no letters, no watermark, no logo.
