LoggerFile.h

/****************************************************************************
 * Platform Abstraction Layer
 * Daryl Borth 2026
 * LoggerFile.h
 *
 * Generic - works unmodified on GC, Wii, and Wii U. All three platforms
 * expose their mounted storage through a standard devoptab path (eg.
 * "sd:/debug.log" on GC/Wii, "/vol/external01/debug.log" on Wii U, or
 * whatever a caller passes in LogConfig::filePath), so a single stdio-
 * based implementation covers every platform. There is nothing 
 * platform-specific left to put behind an interface here.
 *
 * Register this only after FileSystemDriver::init() (and, if the target
 * device is removable, a successful mountStorageDevice() call) has run -
 * Logger::init()/reconfigure() can be called again later once storage
 * becomes available if it wasn't at platform startup.
