 * Alter raw data before it's sent to the API.
 *
 * This hook is for changes that need to be made on-the-fly, before the raw data
 * is sent to the API for processing. Changes will not be persisted to the
 * related Drupal entity. Trying to persist changes here yourself isn't a good
 * idea, the entity is likely to be in the middle of a save operation for this
 * hook to be invoked in the first place.
 *
 * If you need to make persistent changes to the data structure, use core's
 * hook_ENTITY_TYPE_presave() with one of the DX8 config entity types, or
 * an entity type using DX8 layout fields and/or templates.
 *
 * Due to the nature of manipulating data at this level, it's recommended that
 * usage of this hook be limited to advanced use cases only, and alterations be
 * applied with caution and sufficient test coverage.
 *
 * @param array $data
 *   Data to alter.
 * @param \Drupal\Core\Entity\EntityInterface $entity
 *   The entity data is being prepared for.
 * @param $type
 *   The type of operation. Currently one of: "style", "template",
 *   "layout_field", "elements".
