Hi Mark,

Thanks so much for your fantastic article, I’ve been following your work for a while now, and I really appreciate your continued contributions to the Angular community 🙏

If you don’t mind, I’d love to clarify something about how signal-based change detection works under the hood.

In the context of Angular's CD, when you refer to a “node” being marked dirty due to a signal update, does "node" mean the entire component template, or could it refer to a more specific interpolation or binding inside the template?

What I’m really trying to understand is:
How fine-grained is signal-based CD in practice?

Because as I understand it, the component template gets compiled into one function,
so even if only one signal changes, it feels like that whole function would be invoked again, re-evaluating all the interpolations inside.

Would really appreciate any insight you can share and thanks again for the amazing work!
