## Title

    [AI SDK RSC] streamable UI in server action: "Cannot find `div`" / "`Component` refers to a value, but is being used as a type" (file is .ts not .tsx)

## Body

    Cause (Documented platform behavior): JSX is only parsed in .tsx files.
    
    Fix status: documented_behavior
    
    Limitations:
    - exact string is generic; match together with product/context
    
    Other error fragments:
    - Cannot find `div`
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/vercel/ai/5d12eaa6caa193d3901cbab98a734403eb6bf622/content/docs/09-troubleshooting/05-streamable-ui-errors.mdx (official_docs, unknown, documented_behavior): Troubleshooting page: these errors occur because the file ends in .ts instead of .tsx.
    
    Search phrasings: createStreamableUI Cannot find div; refers to a value but is being used as a type ai rsc
    
    Evidence basis (self-declared by the contributing chat client): public_source.
