Create a four-page interior design proposal series titled “Dark Stone Italian Residence”. The project is a dark Italian-style living room for a real private residence. It should feel architectural, refined, expensive and livable — not a hotel lobby, not a showroom, not a commercial lounge. Use a modern interior design studio proposal style: clean editorial layout, structured grid, refined typography, soft shadows, dark section headers, thin divider lines, premium material swatches, short English labels only. Core visual language: charcoal stone feature wall, dark walnut veneer, mocha modular sofa, leather lounge chair, stone coffee table, smoked glass side table, soft greige rug, warm ambient lighting, abstract wall art, ceramic vase, books, tray, candle, indoor plant and subtle champagne metal details. Page 01 / Concept Board: Show a large panoramic living room render as the hero image, with material swatches, color palette, key furniture cutouts and short design notes. Page 02 / Spatial Breakdown: Show a 3D axonometric exploded view of the same living room, explaining the lighting, curtain system, stone wall, walnut storage, sofa zone, lounge chair, coffee table, rug, styling layer and circulation path. Page 03 / Furniture Selection: Show 20 realistic product cutouts in a clean catalog grid: mocha sofa, leather lounge chair, stone coffee table, smoked glass side table, walnut media console, storage cabinet, rug, floor lamp, table lamp, abstract art, ceramic object, vase, books, tray, candle, plant, pillows, curtains, metal bowl and storage box. Page 04 / Material Board: Show close-up detail panels for sofa texture, stone and walnut, coffee table styling, lighting mood, plus material swatches and a color balance chart. Keep the whole series consistent, premium, modern and residential. Avoid brand logos, famous furniture designs, cheap product styling, excessive gold, hotel lobby atmosphere and overly cold showroom feeling. Vertical 4:5 format for each image.
