Isometric SVG office scene

Create a single-file page whose body is one inline SVG illustration: an isometric view of a small law-office room with a desk, a chair, a monitor showing a tiny chart, a bookshelf with at least eight books of varying colors, a window with light falling on the floor, and a potted plant. Use a consistent isometric projection (30 degree axes), a limited palette of six colors plus neutrals, and flat shading with one lighter and one darker face per solid. No raster images. Group elements with <g id> names. Keep the file under 40 KB. Return the complete file in one code block.
