/**
 * Test environment setup — sets default env vars BEFORE any module is loaded.
 *
 * This prevents `src/env.ts` from throwing at import time when required
 * environment variables are absent.  Add this file as a `--preload` argument
 * to `bun test` calls in package.json.
 *
 * Only the 5 env vars that `src/env.ts` considers required are set here.
 * Optional vars (S3_SECRET_KEY, ADMIN_API_TOKEN, etc.) use their own
 * defaults in `src/env.ts` and are not touched.
