Purpose

Provide a Prisma client instance without hard build dependency for CI/standalone builds.

Public Surface

• prisma: PrismaClientLike with minimal typed methods used by routes.

Behavior & Invariants

• Dynamically requires @prisma/client; falls back to a no‑op class if unavailable.
• Caches prisma on global in non‑production.

TODO / Technical Debt

• Replace PrismaClientLike stubs with generated types where available.
