/**
 * Storage path helper.
 *
 * Historically this module also exported a top-level `minioClient`,
 * `ensureBucket()`, and `getPresignedUrl()` that read MINIO_* env vars
 * eagerly at import-time. That broke the Next.js production build
 * (the route-data collection phase imports route modules transitively,
 * and modules touching `env.MINIO_*` blew up under SKIP_ENV_VALIDATION
 * with `InvalidEndpointError: Invalid endPoint : undefined`).
 *
 * Storage config now lives in `system_settings` rows and is read at
 * runtime by the pluggable backend in `@/lib/storage` (see
 * `getStorageBackend()` and `presignDownloadUrl()`). Build-time env
 * vars are no longer the source of truth.
 *
 * The only piece worth keeping in the legacy module path was this pure
 * `buildStoragePath` helper, which doesn't touch env at all and is
 * imported by several services. Everything else has been deleted.
