Field notes
The homepage separates the checker, test sheet, poster preview, and browser-based calculation into distinct tools. Its guide describes a worked example in HTML, with inputs and results readable without running the script. The test sheet covers five real print sizes for phone scanning; the poster preview calls attention to keeping the quiet zone clear of type and trim.
