Heuristic scan rendered at 150 dpi. A run of text counts as hidden when it leaves no ink, falls outside the page box, is smaller than 4pt, or has no contrast against its background. Absence of findings is not a guarantee of safety. This report and the sanitised copy are deleted 60 minutes after the scan.
