Record-State Favicon Previews
These favicons are generated deterministically from GoGuides measurement inputs for the site, including AI Rank and crawl timing. They provide a visual representation of the corresponding GoGuides record state. The same supported inputs produce the same favicon output. If a favicon appears different elsewhere, verify the record here to compare it with the current GoGuides state.
