 * ### Manual Scaling
 * **Example:** Scale the fleet to a fixed size
 * ```typescript
 * // init — bind the operation to the group
 * const setDesiredCapacity = yield* AWS.AutoScaling.SetDesiredCapacity(group);
 *
 * // runtime — set the fleet size, honoring the group's cooldown
 * yield* setDesiredCapacity({ DesiredCapacity: 4, HonorCooldown: true });
 * ```
