Generated via Gemini Pro web UI with "Create image" tool enabled,
uploading a pure black (#000000) 1024x1024 image and prompting
"recreate this as it is". All images verified to contain SynthID
watermarks (confidence 0.52-0.67, carrier strength ~9300-9900).
These reference images are critical for carrier frequency discovery,
phase validation, and improving cross-resolution robustness.
268 black + 281 white pure-color reference images at 864x1184 (4:3
landscape aspect ratio). Generated via gemini-2.5-flash-image model.
This complements the 9:16 portrait images and covers the classic photo
aspect ratio commonly used in Gemini outputs.

This resolution is not covered by the existing codebook and is one of
the most common mobile Gemini output formats.
