[Content]: All code examples have erros

📚 Subject area/topic

/concepts/context.mdx

📋 Page(s) affected (or suggested, for new content)

https://docs.solidjs.com/concepts/context

📋 Description of content that is out-of-date or incorrect

The code examples are inconsistent.
Most (except one or two) will not work like provided on the page.
They lack initialisation lines, are copies of the example above and therefore not working, or have other issues.

There is not one example on the page that explains or shows all the code needed to run contexts.

🖥️ Reproduction in StackBlitz (if reporting incorrect content or code samples)

No response

Start with /concepts/context.mdx, linked from the Solid documentation page, and review each context code example for missing initialization, copied snippets, and other errors. Verify the examples as complete runnable demonstrations, and consider the work done when the page's examples consistently work as presented.
