## Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Confirm the reported code matches JSON parse/stringify deep clone. Check the framework context and diagnostic message before suppressing it.

## Fix prompt

Use this once validation confirms the diagnostic is real.

Replace `JSON.parse(JSON.stringify(value))` with `structuredClone(value)`. It is faster and preserves Dates, Maps, Sets, and cyclic references.
