# Next.js frontend workload for the first production deployment: serves pages,
# static assets, and SSR only. All /api, /uploads, and /generated-results
# traffic is routed to zhinian-go-api by the Ingress, so this workload holds no
# RDS credentials and needs only the shared session secret for local cookie
# verification in the middleware.
