Wire up Sentry on both the Next.js front-end and the Node/Edge server side. Capture client errors with source maps, server runtime errors, slow API spans, and Web Vitals. Tag every event with org_id and project_id so support can filter by tenant. Tie commits to releases via the Sentry CLI in deploy/deploy.sh, enable Cron monitoring for scheduled jobs (digest emails, AI background jobs), and add a Report this link in the global error boundary. Optional PR comments for new errors introduced by a change.
