AI Prompt for Photorealistic FACS Expression Grid with 15 Panels

"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 {argument name="grid layout" default="15 panels arranged in 3 rows and 5 columns"} showing the same {argument name="subject" default="realistic young female student"} repeated in every panel with identical framing, lighting, hairstyle, and {argument name="outfit" default="white school shirt with a gray ribbon tie"}. Apply a different subtle facial-expression change to each panel based on these {argument name="FACS action units" default="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."
