Structure React 19+ components following best practices for organization, state management, props handling, and code readability with top-down structure and single responsibility principle. Use this skill when creating new React components, refactoring existing components, organizing component logic, managing component state, defining prop interfaces (IComponentProps with I prefix), or implementing component patterns. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend component implementations. This skill ensures predictable top-down structure (imports → types/interfaces → component → hooks → derived values → JSX), proper props destructuring with defaults in function signature, manageable component size (split at >300 lines), composition via Shadcn Slot pattern (asChild prop), React 19 patterns (use() hook for promises, useActionState for forms, useOptimistic for immediate feedback), no manual useMemo/useCallback (React Compiler handles memoization), Server Compo
