## Description

Use context selector is a state management library that allows applications to share state across component trees without prop drilling or unnecessary re-renders. It provides a specialized React context creation mechanism alongside hooks for reading targeted context slices, ensuring that components update only when their specific data changes.

The library features granular dependency tracking and selector-based subscriptions to prevent sluggish rendering caused by broad state updates. It also includes cross-root context bridging to connect isolated component trees under a single provider and wraps state modification functions to maintain synchronization during concurrent rendering cycles.
