## Description

This project provides a React hook for synchronizing component state with browser storage, ensuring data persists across page reloads and browser sessions. It is designed to manage persistent application state while providing hydration-safe initialization to prevent mismatches during the transition from server-side rendering to client-side execution.

The library distinguishes itself by including a fallback manager that detects when browser storage is inaccessible, automatically switching to an in-memory state to maintain application continuity. It also supports cross-tab synchronization by listening for global storage events, ensuring that state changes are propagated across multiple browser windows or iframes.

Beyond basic persistence, the system includes tools for monitoring storage availability and tracking whether data currently resides on disk or in memory. Developers can also implement custom serialization logic to handle complex data structures that exceed standard formatting requirements, and utilize built-in functions to reset stored data to its default values.
