Ben Ren 7bf9545df9 Add validation results for new codebook profiles ...

4 test images generated via Gemini API with real content:
  - 2x 9:16 (cat, mountain) at 1344x768
  - 2x 4:3 (coffee, city) at 864x1184

V3 bypass results with expanded codebook:
  | Image          | Resolution | PSNR    | SSIM   | Exact Match |
  | city (4:3)     | 864x1184   | 45.7 dB | 0.9972 | yes         |
  | coffee (4:3)   | 864x1184   | 50.0 dB | 0.9981 | yes         |
  | cat (9:16)     | 1344x768   | 50.2 dB | 0.9978 | yes         |
  | mountain (9:16)| 1344x768   | 49.1 dB | 0.9971 | yes         |

PSNR/SSIM are excellent. Phase coherence drop is near-zero, suggesting
the API-generated images may have weaker watermark embedding than
web-UI outputs, or the carrier extraction needs further tuning.
