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>

//! Headless screenshot of the real PdfCraft shell (egui_kittest + wgpu, no window needed).
|
||
//!
|
||
//! ```text
|
||
//! cargo run -p pdfcraft-ui-egui --example shot -- out.png [file.pdf] [--size 1440x900] [--scale 2] [--page 3 --panel pages …]
|
||
//! ```
|
||
//! `--width N` downscales the image to N pixels wide (README screenshots). Any other
|
||
//! `--key value` pair is passed to `PdfCraftApp::set_option`
|
||
//! (the same verbs as the desktop app's command-line flags and the future control channel).
