pages.signIn is meant to point at a CUSTOM sign-in page. Setting it to '/api/auth/signin' — Auth.js's own built-in endpoint — makes Auth.js redirect there whenever it wants the sign-in page, which is the same endpoint, producing ERR_TOO_MANY_REDIRECTS in browsers. Omitting the setting falls back to Auth.js's default sign-in handler, which renders the provider-picker HTML at /api/auth/signin instead of redirecting.
