mrshankargupta-lang/ai-house ? reverse-engineered prompt

Build me a simple web app that lets me view and work with house floor plan files.

I want to load a house plan in the browser, see it drawn clearly on a canvas or page, and be able to switch between a few saved versions of the plan. It should also show useful details from the plan data, and let me export or regenerate the plan image if needed.

If there are validation files or checks for the plan data, include those too so I can tell when a plan file is correct. Keep it easy to run locally, and make the main page clean and straightforward, with the house layout as the focus.

If you need to, look up current docs online for any browser or canvas details, and then wire everything together so I can open it and immediately see the plan working.
