 * @typedef {Object} TransformersEnvironment
 * @property {string} version This version of Transformers.js.
 * @property {{onnx: Partial<import('onnxruntime-common').Env>}} backends Expose environment variables of different backends,
 * allowing users to set these variables if they want to.
 * @property {boolean} allowRemoteModels Whether to allow loading of remote files, defaults to `true`.
 * If set to `false`, it will have the same effect as setting `local_files_only=true` when loading pipelines, models, tokenizers, processors, etc.
 * @property {string} remoteHost Host URL to load models from. Defaults to the Hugging Face Hub.
 * @property {string} remotePathTemplate Path template to fill in and append to `remoteHost` when loading models.
 * @property {boolean} allowLocalModels Whether to allow loading of local files, defaults to `false` if running in-browser, and `true` otherwise.
 * If set to `false`, it will skip the local file check and try to load the model from the remote host.
 * @property {string} localModelPath Path to load local models from. Defaults to `/models/`.
 * @property {boolean} useFS Whether to use the file system to load files. By default, it is `true` if available.
 * @property {boolean} useBrowserCache Whether to use Cache API to cache models. By default, it is `true` if available.
 * @property {boolean} useFSCache Whether to use the file system to cache files. By default, it is `true` if available.
 * @property {string|null} cacheDir The directory to use for caching files with the file system. By default, it is `./.cache`.
 * @property {boolean} useCustomCache Whether to use a custom cache system (defined by `customCache`), defaults to `false`.
 * @property {import('./utils/cache.js').CacheInterface|null} customCache The custom cache to use. Defaults to `null`. Note: this must be an object which
 * implements the `match` and `put` functions of the Web Cache API. For more information, see https://developer.mozilla.org/en-US/docs/Web/API/Cache.
 * @property {boolean} useWasmCache Whether to pre-load and cache WASM binaries for ONNX Runtime. Defaults to `true` when cache is available.
 * This can improve performance by avoiding repeated downloads of WASM files. Note: Only the WASM binary is cached.
 * The MJS loader file still requires network access unless you use a Service Worker.
 * @property {string} cacheKey The cache key to use for storing models and WASM binaries. Defaults to 'transformers-cache'.
