## Validation prompt

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

Confirm the reported code matches Browser global read during server render. Check the framework context and diagnostic message before suppressing it.

Use this once validation confirms the diagnostic is real.

Move browser-only reads into an effect or event, guard them behind a client-only render path, or use useSyncExternalStore with a stable server snapshot.
