joyfish666/WordCraft ? reverse-engineered prompt

Build me a browser only app where I can type one simple sentence about a house, like “three bedrooms, a living room, and a kitchen with a master bath,” and it turns that into an editable 3D home layout. I want the result to be local first, with everything stored in the browser, and the main experience should feel clean and minimalist, with a warm paper like look.

The app should let me switch between a 3D view and a top down plan view, then edit rooms, walls, doors, windows, and furniture by dragging or using a simple properties panel. I want undo and redo, a sample or example state for first time visitors, a bottom chat area for refining the design, and a way to save or share the model with a screenshot and a restore code. If an AI key is needed, make a simple settings area for it, and keep the whole thing frontend only. Use current docs online if you need to.
