Description

A passkey used to establish a parent-child relationship between a RenderTarget and a Viewport.

This struct uses the passkey idiom to restrict the calling of `Viewport::setRenderTarget` to friend classes (specifically `helios::rendering::RenderTarget`), ensuring that the ownership hierarchy is managed correctly.
