Create a detailed floor plan of an Italian Renaissance palace. The design should include classic architectural features such as large central courtyards, symmetrical layout, and rooms organized around the main courtyard. Include grand hallways, multiple rooms with high ceilings, and arcades with columns. The plan should also show areas like private living quarters, a grand staircase, and spaces for public gatherings. Ensure the architectural style reflects the elegance and harmony typical of Renaissance palaces, with balanced proportions and clear geometries."
