Use named imports in the dynamic import of @sentry/react so the bundler
can drop re-exported modules we never reference (replay 207K, feedback 67K,
replay-canvas 25K). Also set defaultIntegrations: undefined to prevent
Sentry from pulling those modules at runtime.
Sentry chunk: 431K → 128K (-70%).
The replay integration hooks into every DOM mutation via rrwebWrapped
event listeners, adding ~133ms of overhead during heavy re-renders.
We only use Sentry for error reporting, not session replay.
Sentry SDK is loaded via dynamic import() only when a DSN is configured
and error reporting is enabled, keeping it out of the initial bundle.
Users can control error reporting via a toggle and DSN field in
Advanced Settings, with the DSN synced across devices via encrypted
NIP-78 settings. The ErrorBoundary now reports fatal crashes to Sentry
with component stack context, and a beforeSend hook censors nsec
private keys before any data leaves the browser.
