[Suggestion]: add explanation & illustration for the Note in the 'Passing state deeply with context' chapter

Summary

Currently, in the Note, it says "This example uses heading levels because they show visually how nested components can override context.". However, it is unclear what this sentence means. What does it mean for a nested component to override context? I suspect that 'because they show visually how nested components can override context' is not correct, or if correct, it needs clear explanation what it means, because I personally don't get it (and I don't want to ask GPT to get a wrong answer...).

If left unchanged, this sentence risks confusing millions of learners in my opinion (myself included).

Details

The sentence "This example uses heading levels because they show visually how nested components can override context." is not explained. It would be useful to explain this much more explicitly. It's like throwing a sentence at a super abstract level... (which is not helpful for learners).

Start with the “Passing data deeply with context” page linked in the issue and read the Note around the sentence about heading levels and nested components overriding context. Clarify the statement with an explanation and illustration showing what the example demonstrates; done means learners can understand the relationship without needing outside explanation.
