 All components in the system are composed into a rooted

 declaring instances of other components as their children and providing them
 with capabilities. At the same time, child components can expose capabilities
 back to the parent. These component instance and capability relationships make
 up the **component topology**.

 Any parent component and all its children form a group within the tree called a

 external components dependent on its exposed capabilities.

 The parent component declares the set of child components in the realm and
 routes capabilities to them using the `offer` keyword. In this way, the parent
 determines both the scope and the source of each child's capabilities. This also
 enables multiple components in the topology to provide the same capability, as
 the component framework relies on explicit routes to determine how to resolve
