* ============================================================================
* Auth.js v5 — PLACEHOLDER configuration for the scaffold phase.
* ============================================================================
*
* The Credentials provider below accepts ANY email that exists in the User
* table (seeded by `pnpm db:seed`). NO PASSWORD CHECK is performed. This is
* deliberately minimal — just enough to populate the tRPC context with a real
* Auth.js session — and MUST be replaced with real authentication before any
* non-dev deployment.
*
* Auto sign-in
* ------------
* See `resolveUser()` below. When AUTH_DEV_AUTOLOGIN=true, server-side code
* that has no session falls back to the seeded admin user. This is a back
* door and is gated by an explicit env flag whose default in .env.example is
* FALSE.
*
* !!! NEVER set AUTH_DEV_AUTOLOGIN=true in production. !!!
*
* In production with AUTH_DEV_AUTOLOGIN unset/false, requests without a
* signed Auth.js session resolve to user=null, and protectedProcedure throws
* 401.
* ============================================================================
