## Description

Level is a database library that provides a unified interface for managing sorted key-value data. It functions as an abstraction layer that allows applications to store and retrieve binary information consistently across server-side environments and web browsers.

The project utilizes a modular architecture that supports pluggable storage backends, enabling the system to adapt to different host environments while maintaining identical behavior. By organizing data in lexicographical order, it facilitates efficient range queries and ordered retrieval. The library handles large datasets through asynchronous stream processing, ensuring that read operations do not block the main execution thread.

This system supports embedded database management, allowing developers to integrate persistent storage directly into applications without the need for a separate database server. It is designed to support offline-first development by enabling local data persistence within the browser.
