## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Replace single-click-to-pan with selector as the default canvas tool. Left-click-drag on background draws a blue marquee rectangle to select multiple shapes. Shift/Ctrl+click toggles additive selection. Panning moves to Space+drag, middle-click, or wheel/trackpad. Delete/Backspace removes all selected shapes. folk-shape highlighted state shows blue selection outline.
