Minimal but real App Router app that builds (next build exit 0):
- src/lib/auth.ts: NextAuth v5 Credentials provider calling checkLogin()
(argon2id/bcrypt + md5->argon2id upgrade gated by CONVERT_PASSWORDS), JWT
session, /api/auth/[...nextauth] route handler.
- src/app: root layout, home (force-dynamic, reads hotel_name via siteSettings),
/login client form (signIn).
- next.config.ts: pinned turbopack.root, serverExternalPackages for the Prisma
MariaDB adapter; tsconfig set up for Next.
Routes: / (dynamic), /login, /api/auth. Verified: next build exit 0, 28 tests.
Still needs DB+APP_KEY to run auth end-to-end. i18n/middleware/pages to follow.
