Why Children Need @Binding

Understand two-way data flow between views.

Two Views, One Truth

When a parent owns a value and a child needs to change it, they must share one source of truth. Otherwise they drift apart. 🔗

The Problem with Copies

If you just pass a value into a child, the child gets a copy. Editing that copy never touches the parents original data.
