I'll write comprehensive unit tests for shared UI components in frontend/cmmty/components/ using React Testing Library and Jest. I'll cover Button, Input, Modal, Toast, Badge, and Skeleton with at least 3 test cases each covering renders correctly, handles user interaction, and shows correct states (loading/error/disabled). I'll achieve 80%+ line coverage and ensure all tests pass with npm test from the frontend root. All files strictly inside frontend/cmmty/. Ready.
