IA Disclosure

Only one thing has been made by a LLM and its the current theme. I could create a good one (see isaaconnect for the implementation of good themes. Colors of isaaconnect has been made by biobak, not me). The interface (placements, boxes, etc.) has been made by me though. Only colors, shadows, etc. is created by a LLM.
