FACS Action Unit Reference Grid

Goal: Create a clean reference-sheet infographic titled FACS Action Unit Reference Grid, showing a realistic female character expression sheet for Facial Action Coding System action units.

Canvas: Square 1:1 white canvas, approximately 1024 x 1024 px, with a centered black title at the top and a smaller subtitle reading Realistic Female Character Expression Sheet. Use a plain academic reference-chart layout.

Layout: Below the title, create an exact 7-column by 7-row grid with thin light-gray borders, for exactly 49 individual portrait cells. Each cell contains one small bust portrait centered above a tiny caption line. Keep spacing uniform and margins narrow. The portraits should all be the same realistic young adult woman with shoulder-length black hair with a center part, slightly wavy ends, wearing a simple dark top, front-facing unless the label requires a head turn, tilt, up, down, forward, or back. The face area should be softly anonymized or blurred with a skin-tone rectangular blur while preserving hair silhouette, head angle, and overall expression-reference pose.

Visual style: Photorealistic character-sheet thumbnails, neutral studio lighting, white background, consistent scale, realistic hair detail, minimal shadows, scientific reference grid aesthetic. Typography is small black sans-serif text; captions should fit inside each cell.

Text content: Include exactly 49 labeled cells, numbered left to right, top to bottom. Use these exact visible English labels in order: 1. AU1 Inner Brow Raiser; 2. AU2 Outer Brow Raiser; 3. AU4 Brow Lowerer; 4. AU5 Upper Lid Raiser; 5. AU6 Cheek Raiser; 6. AU7 Lid Tightener; 7. AU9 Nose Wrinkler; 8. AU10 Upper Lip Raiser; 9. AU12 Lip Corner Puller; 10. AU14 Dimpler; 11. AU15 Lip Corner Depressor; 12. AU17 Chin Raiser; 13. AU18 Lip Pucker; 14. AU20 Lip Stretcher; 15. AU23 Lip Tightener; 16. AU25 Lips Part; 17. AU26 Jaw Drop; 18. AU27 Mouth Stretch; 19. AU41 Lid Droop; 20. AU42 Slit Eyes; 21. AU43 Eyes Closed; 22. AU44 Squint; 23. AU45 Blink; 24. AU46 Wink; 25. AU51 Head Turn Left; 26. AU52 Head Turn Right; 27. AU53 Head Up; 28. AU54 Head Down; 29. AU55 Head Tilt Left; 30. AU56 Head Tilt Right; 31. AU57 Head Forward; 32. AU58 Head Back; 33. AU61 Eyes Left; 34. AU62 Eyes Right; 35. AU63 Eyes Up; 36. AU64 Eyes Down; 37. AU82 Nostril Dilator; 38. AU83 Nostril Compressor; 39. AU85 Tongue Out; 40. AU1+2 Surprise Brows; 41. AU4+7 Tense Eyes; 42. AU6+12 Genuine Smile; 43. AU12+25 Open Smile; 44. AU15+17 Sad Mouth; 45. AU14+4 Worried Brow; 46. AU9+10 Disgust; 47. AU20+25 Fear Tension; 48. Neutral Face; 49. Comparison Face.

Subject details: The character is a realistic young East Asian woman. Maintain consistent identity, hair, lighting, and crop across all 49 cells, with only the action unit, gaze direction, or head pose changing according to the caption.

Constraints: Use exactly 49 cells and no extra thumbnails. Keep the chart monochrome and white aside from realistic portrait colors. Do not add logos, watermarks, decorative icons, or extra explanatory paragraphs. Make the title large and readable, while individual captions are tiny but structured like a reference grid.
