## Validation prompt

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

Confirm the reported code matches Locale/timezone formatting during render. Check the framework context and diagnostic message before suppressing it.

## Fix prompt

Use this once validation confirms the diagnostic is real.

Format locale/timezone-dependent values in a post-mount useEffect + state, or pass an explicit locale and timeZone so the server and the browser render the same text. Only runs on SSR-capable projects.
