+
+**Add canvas keyboard shortcuts (undo/redo/delete/select-all/deselect) and verify full integration — 71 tests pass, zero TypeScript errors**
+
+## What Happened
+
+Added a useEffect with window-level keydown listener to DesignCanvas.tsx implementing five keyboard shortcuts: Ctrl+Z (undo), Ctrl+Shift+Z/Ctrl+Y (redo), Delete/Backspace (remove selected), Escape (deselect all), Ctrl+A (select all). Handler guards against firing when an input/textarea/select element is focused. Unwrapped the _removeObject alias to removeObject for the delete handler. Both tsc and vitest pass cleanly — 71 tests across 6 files, zero TypeScript errors.

+## Verification
+
+npx tsc --noEmit: zero errors (exit 0). npx vitest run --reporter=verbose: 71 tests pass across 6 test files (exit 0).
