d3db99818f
The app, crates, binaries, bundle id, packaging, icons, screenshots and docs are now PdfCraft / pdfcraft (repo storytold/pdfcraft). On first launch the desktop app moves the PrintCraft settings and crash-recovery folders to the new name, and both apps read settings saved under the old storage key, so upgrades keep recent files, preferences and unsaved work. The signing test fixtures keep their PrintCraft subject names (they are binary). Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
