Production caveat: National identity login is production-gated by Singpass onboarding. Keep OIDC client secrets server-side and validate every token (issuer, audience, expiry, nonce) exactly as documented before trusting an identity claim.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
