爆炸轴测图：楼层与系统的垂直分解

Create an exploded axonometric diagram of a small building, its layers pulled apart vertically along a common axis. Show, from bottom to top with even gaps between them: the site and landscape plane, the foundation and ground floor slab, the ground floor plan with walls and furniture, the upper floor, the structural frame drawn as a skeleton of columns and beams only, the facade skin as a separate translucent layer, and the roof floating at the top. Detail thin dashed vertical guide lines connecting the corresponding corners of every layer so the assembly logic is clear. Render everything in a restrained palette: pale warm grey solids, white surfaces, one accent colour for the structural frame, and thin dark outlines throughout. Add small leader lines with sans-serif labels naming each layer. Keep the axonometric angle consistent, with no perspective convergence. Flat architectural diagram, white background, no shadows, no texture, no photorealism.
