/**
 * This module provides a pre-instantiated WebAssembly-based implementation of
 * the Brotli decompression algorithm, originally developed by Google for the
 * WOFF2 font format's compression.
 *
 * The decompressor is implemented in Rust, compiled to WebAssembly, and
 * wrapped in a dead-simple TypeScript API. It's designed to be as small and
 * fast as possible, with a minimal API surface and no external dependencies.
 *
 * **Note**: if the decompressor receives an invalid or uncompressed input, it
 * will quietly return the input buffer as-is. This is a feature, not a bug.
 *
 * @example
 * ```ts
 * import { decompress } from "@nick/brotli";
 *
 * const compressed = new Uint8Array(
 *   [0x1b, 0x5e, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00],
 * );
 * const decompressed = decompress(compressed);
 *
 * console.log(decompressed);
 * // Uint8Array [ 27, 94, 0, 0, 0, 0, 0, 0 ]
 * ```
