/**
 * Runtime binding for `controltower:ListLandingZones`.
 *
 * An account-level operation that returns the organization's landing zone
 * ARN (a landing zone is a singleton — the list has at most one entry).
 * Useful for governance functions that discover the landing zone before
 * reading its drift status. Provide the implementation with
 * `Effect.provide(AWS.ControlTower.ListLandingZonesHttp)`.
 * ### Inspecting the Landing Zone
 * **Example:** Discover the Landing Zone ARN
 * ```typescript
 * // init — account-level binding takes no resource
 * const listLandingZones = yield* AWS.ControlTower.ListLandingZones();
 *
 * // runtime
 * const result = yield* listLandingZones();
 * const arn = result.landingZones[0]?.arn;
 * ```
 *
