照片真实的 FACS 表达网格

Using REFERENCE_0 and REFERENCE_1 as the FACS action-unit guide, create a photorealistic expression-control test sheet instead of an illustrated chart. 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 these AU1, AU2, AU4, AU5, AU6, AU7, AU9, AU10, AU12, AU15, AU17, AU20, AU23, AU24, AU25, while preserving identity consistency and keeping the changes limited to the face. Use a close-up front-facing portrait crop from upper chest to top of head, natural outdoor backlight, shallow depth of field, and thin white dividers between panels. Do not include any chart titles, labels, AU text, explanations, or Japanese text.
