Architecture

src-tauri/src/
  main.rs              # App entry, tray icon, shortcuts, per-monitor overlay windows
  commands/            # Tauri IPC commands (screenshot, window, file, ocr, translate)
  services/            # Business logic (screen capture, OCR, translate)

src/
  App.tsx              # Main UI — selection, annotations, toolbar, OCR, translate
  styles.css           # Global styles

Multi-monitor: Each monitor gets its own transparent overlay window. The main overlay handles selection and annotation; secondary overlays show dim effect only. Windows synchronize via Tauri events (selection-locked, cancel-capture).

Keyboard Shortcuts

Shortcut	Action
Cmd+Shift+A	Take screenshot (customizable)
Escape	Cancel capture
Cmd+Z	Undo last annotation
Cmd+C	Copy selected OCR text
Delete	Delete selected annotation
Shift (hold)	Constrain shapes (square/circle/snap angles)
