interface PageVariantInterface in Drupal 10

Provides an interface for PageDisplayVariant plugins.

Page display variants are a specific type of DisplayVariant, intended for "pages", which always have some main content to be rendered. Hence page display variants may choose to render that main content in a certain way: decorated in a certain way, laid out in a certain way, et cetera.

For example, the \Drupal\block\Plugin\DisplayVariant\FullPageVariant page display variant is used by the Block module to control regions and output blocks placed in those regions.
