- A press with a selection tool inside an artboard makes it the active one, as the Artboard tool's does; before, only the navigator and the Artboards panel changed it. - Paste in Place, in Front and in Back take `artboard` (the UI passes the active one): the objects go where they were on the artboard they were copied from, on that artboard. Without it, they paste where they were, as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! VectorCraft's egui frontend: an Illustrator-style UI over `vectorcraft-engine`.

//! The UI is thin: every action goes through [`VectorcraftApp::run`], which dispatches UI commands
|
||
//! (view/window) here and everything else to the engine. The same entry point serves menus,
|
||
//! shortcuts, the ⌘K palette and the control channel ([`control`]).
