15/// A marker trait for types that can be used as components in the ECS.
16///
17/// This trait must be implemented for any struct you wish to attach to an entity.
18/// The `'static` lifetime ensures that the component type does not contain any
19/// non-static references, and `Send + Sync` are required to allow the component
20/// data to be safely accessed from multiple threads.
