// @prisma/client di-require() secara lazy di dalam fungsi — BUKAN static import di atas.
//
// Root cause SIGSEGV di cPanel (berlapis):
//   1. Static `import { PrismaClient } from '@prisma/client'` memuat kode inisialisasi
//      Prisma (termasuk registrasi signal handler untuk binary engine) pada saat
//      modul pertama kali di-import oleh build worker.
//   2. Ketika build worker exit setelah "Collecting page data", signal handler tersebut
//      meng-akses state yang sudah di-free → SIGSEGV.
//
// Fix: require() hanya dipanggil saat query pertama dieksekusi di server runtime.
// Saat build, Proxy mengembalikan fungsi no-op sehingga @prisma/client tidak pernah dimuat.
