/**
 * @file storage_sd.h
 * @brief Narrow SD-card storage wrapper built directly on FatFs.
 *
 * Architectural note:
 * An earlier storage layer mixed allocation-heavy tutorial helpers with
 * application-specific policies. This service now exposes only the minimal
 * file-oriented operations needed by profile loading and streamed profile
 * saving, while keeping FatFs details out of higher-level services.
