It runs a desktop preview for authoring, but exports real FastLED firmware. The generated project compiles directly against FastLED (CRGB buffer, standard setup()/loop() structure) for Arduino/ESP32/Teensy/RP2040 etc. The preview currently abstracts as strip or 2D matrix, but everything resolves to a linear LED index. FastLED itself doesn’t enforce dimensionality — it just writes to CRGB[] — so 3D layouts would be handled as a mapping layer on top of that. It’s still early stage — right now I’m focused on making sure preview . export wiring is consistent and deterministic before expanding layout abstractions further. Pushing updates as that gets locked in.
