### Full prompt
```text
Using the reference photos as the FACS action-unit guide, create a photorealistic expression-control test sheet. Generate [15 panels arranged in 3 rows and 5 columns] showing the same [realistic young female student] repeated in every panel with identical framing, lighting, hairstyle, and [white school shirt with a gray ribbon tie]. Apply a different subtle facial-expression change to each panel based on [AU1, AU2, AU4, AU5, AU6, AU7, AU9, AU10, AU12, AU15, AU17, AU20, AU23, AU24, AU25], preserving strict identity consistency with all changes confined to the face. Framing is a close-up front-facing portrait crop from upper chest to top of head, with natural outdoor backlight, shallow depth of field, and thin white dividers between panels. No chart titles, labels, AU codes, text, or Japanese characters.
