dkdc-draw 0.1.0

# draw

Local-first, sketch-style drawing tool. Excalidraw-inspired, built on Rust with a vanilla JS frontend.

Single binary. No cloud. Your drawings live in `~/.config/draw/drawings/`.

- **Sketch-style fills**: hachure (diagonal lines), cross-hatch, solid, none
- **Full interactions**: drag, resize, multi-select, rubber band, pan (scroll/space+drag), zoom (ctrl+scroll)
- **Undo/redo**: all operations, including batched multi-element changes
- **Copy/paste/duplicate** with proper ID remapping
- **Z-ordering**: bring to front/back/forward/backward
- **Styles**: stroke color/width/dash, fill color/pattern/density, opacity, font
- **Export**: SVG and PNG
- **Document management**: auto-save, dirty indicator, rename, list
- **Desktop app**: native window via webview (same UI, no browser needed)
- **Python bindings**: `import dkdc_draw`
- **Keyboard-driven**: full shortcut set, `?` for help overlay
