Interface LaravelUi5\Core\Ui5\Dashboard\Contracts\Payload

Marker narrowing {@see WireElement} to tile-content shapes — the switchable content controls that go inside a sap.m.TileContent's content aggregation (sap.m.NumericContent, sap.m.ImageContent, sap.m.NewsContent, …).

Mind the three levels: a {@see Tile} root (GenericTile/ActionTile) holds {@see \LaravelUi5\Core\Ui5\Controls\Sap\M\TileContent} wrappers in its tileContent aggregation, and each TileContent holds one Payload in its content. Payload marks that innermost content control — never a tile root, never the wrapper. Each concrete Payload is an AbstractControl subclass that additionally implements Payload; the wire shape stays the flat {ui5Class: properties} literal.
