I think this is good enough to iterate with.

Thanks so much for this! 🙏 It's super helpful 😄

Reviewed it from a high-level POV, avoided nitpicking.

Left clarification suggestions and a few questions, which are focused on increasing the clarity and hence practical usefulness of this document going forward.

The only thing I definitely want to see changed is `Component`: What we would refer to in technical terms as a `Component instance`. — that's too confusing, and in fact led to a lot of confusion when reviewing the designs.
Everything else is essentially clarifying. It'll probably take you <15 mins to address :)
