+
+- `set<T>(key: string, value: T): void` - Stores a value in localStorage with automatic JSON serialization. Supports objects, arrays, and primitive types. Safe for SSR environments.
+- `get<T>(key: string): T | null` - Retrieves a value from localStorage with automatic JSON parsing. Returns null if key doesn't exist or parsing fails. Type-safe with generic support.
+- `remove(key: string): void` - Removes a specific item from localStorage. Safe for SSR environments.
+
+**Features:**
+
+- 🔒 **SSR Safe**: All methods handle server-side rendering environments gracefully
+- 📦 **Type Safe**: Full TypeScript support with generics
+- 🛡️ **Error Handling**: Comprehensive error handling with automatic cleanup of corrupted data
+- 🔄 **Auto Serialization**: Automatic JSON serialization/deserialization for complex data types

 - `debounce<T>(fn: T, delay?: number): (...args: Parameters<T>) => void` - Creates a debounced function that delays execution until after a specified delay (default 300ms) has passed since its last invocation
