// P4 boards: same full-store adoption as useSdStorage(), but on the SD_MMC slot.
// The internal FFat 'locfd' has a broken FAT metadata layer (f_stat/exists lie —
// see the tile-cache notes), and the exists()-gated identity + prefs loads that
// "worked" at -Og read different garbage at -Os and came up empty: fresh node
