Authors tilemaps in Tiled, drops the exported .tmj map and any external .tsj tilesets into the project’s assets/ folder, and the editor bakes them to a fixed-layout binary (.dtilemap / .dtileset) optimised for SD card streaming on ESP32 and direct mmap-style reads on desktop.
Every component it adds, every exported property and its changelog are in the deki-tiledmapeditor-integration reference.
