/**
 * Defines the entity view mode configuration entity class.
 *
 * View modes let entities be displayed differently depending on the context.
 * For instance, a node can be displayed differently on its own page ('full'
 * mode), on the home page or taxonomy listings ('teaser' mode), or in an RSS
 * feed ('rss' mode). Modules taking part in the display of the entity (notably
 * the Field API) can adjust their behavior depending on the requested view
 * mode. An additional 'default' view mode is available for all entity types.
 * This view mode is not intended for actual entity display, but holds default
 * display settings. For each available view mode, administrators can configure
 * whether it should use its own set of field display settings, or just
 * replicate the settings of the 'default' view mode, thus reducing the amount
 * of display configurations to keep track of.
 *
 * @see \Drupal\Core\Entity\EntityDisplayRepositoryInterface::getAllViewModes()
