What it does
Implements IDekiSDCard and an SDCardComponent. On embedded targets the card is mounted at boot using the configured SDMMC or SPI pins; on desktop, asset reads fall back to the regular filesystem.
The export step in the Deki Editor writes the project’s storage/ folder (GUID table, .dtex textures, .prefab MessagePack scenes, baked fonts, baked .dtilemap / .dtileset if Tiled is in use) in a layout that drops straight onto an SD card and boots.
