Pre-Screen is for collectors who want a structured photo walkthrough before sending a card into deeper review. It keeps the work focused on evidence that can be seen from the uploaded image: card boundary setup, an approximate centering estimate, corner observations, edge observations, and a final summary of what was checked or skipped.

The workflow is most useful when the card is photographed straight on with all four edges visible. A clean photo lets the boundary setup and loupe-style corner checks work from better source information. If the photo is angled, cropped, dark, compressed, or covered by glare, treat the resulting notes as lower confidence and consider taking a new image.

Pre-Screen does not promise a grade, authenticate a card, or inspect hidden surface texture that is not visible in the photo. Use it as a practical first pass before the Card Review tool, the precise Centering workspace, or your own hands-on inspection.
