/**
 * Singleton PrismaClient against the hermetic test DB (DATABASE_URL from .env.test, loaded by
 * setup/load-env.ts). Used by:
 *   - the fixture seeder (fixtures/seed-core.ts), and
 *   - "direct-instantiation" specs for services behind the IAM/RabbitMQ wall (BookingsService,
 *     PaymentsService, WalletService, …) which cannot be booted through their Nest modules because
 *     those transitively import the @tria-plc IAM stack (ESM-only `file-type`) / golevelup RabbitMQ.
 *     Those specs `new TheService(prisma, ...mockedCollaborators)` and assert the money logic.
