/**
 * Runtime binding for `s3:CreateMultipartUpload`.
 *
 * Starts a multipart upload and returns the `UploadId` that `UploadPart`,
 * `CompleteMultipartUpload`, and `AbortMultipartUpload` reference. Use it for
 * objects too large for a single `PutObject` (parts are 5 MiB–5 GiB, uploaded
 * independently and in parallel). Provide the implementation with
 * `Effect.provide(AWS.S3.CreateMultipartUploadHttp)`.
 * ### Multipart Uploads
 * **Example:** Start a Multipart Upload
 * ```typescript
 * // init — bind the operation to the bucket
 * const createUpload = yield* AWS.S3.CreateMultipartUpload(bucket);
 *
 * // runtime — object-level metadata (ContentType, etc.) is set here,
 * // not on the individual parts
 * const { UploadId } = yield* createUpload({
 *   Key: "backups/archive.tar",
 *   ContentType: "application/x-tar",
 * });
 * // pass UploadId to AWS.S3.UploadPart / CompleteMultipartUpload
 * ```
 *
