## Implementation Complete ### Changes Made 1. **Added logout icon** to Icon.tsx (src/components/atoms/Icon/Icon.tsx:78, 779-788) - Added 'logout' to IconName type - Added SVG path for logout icon (arrow pointing out of a door/box) 2. **Added logout button** to App.tsx sidebar (src/App.tsx:24, 97-107, 110-116) - Imported logout API function from backend.ts - Created handleLogout async function that calls logout() API and redirects to /login - Added Sign Out nav item to secondaryNavItems with icon, label, onClick handler, and tooltip ### How It Works 1. User clicks 'Sign Out' button in sidebar secondary navigation 2. handleLogout() is called which: - Calls the logout() API function (POST to /auth/logout) - Backend clears the JWT cookie - Frontend navigates to /login page 3. Error handling: Even if logout API fails, user is still redirected to login page ### Verification - TypeScript compiles with no errors - Logout button visible in browser with correct icon and tooltip - Clicking Sign Out redirects to /login page - Logout API returns success (HTTP 200) ### Files Modified - src/src/components/atoms/Icon/Icon.tsx - Added logout icon - src/src/App.tsx - Added logout handler and nav item
