Use case: ui-mockup. Asset type: premium brandless Microsoft 365 / Fluent-inspired 3D desktop project-management dashboard showcase. Create a precise 3:4 portrait composition on a solid opaque pale cool-gray background. The final raster must be fully flattened RGB with no alpha channel and no transparent canvas. Show one enormous white desktop application window floating at a three-quarter overhead angle, tilted slightly clockwise and cropped along the right edge. At upper-left use an anonymous avatar labeled “Alex / Good morning”; beneath it place “MENU” with raised pills “Dashboard”, “Projects”, “Today’s Tasks”, “All Tasks”, “Calendar”, highlighting Dashboard in pale productivity blue. Add a “TEAMS” block with anonymous member avatars. Across the top place “Find your tasks, projects…”. In the main area show “Projects”, “You have 4 projects”, “+ Add”, then an electric-blue “Studio Team” card and near-black “Product Redesign” card. Both display “Progress”, “55%”, segmented bars, anonymous avatars and “Sep 20, 2026”. Below add “Calendar / Teams / Favorite”, day 20 highlighted and an event bar “Signup flow redesign”. Show only a cropped sliver of a secondary panel at right. Outside the window place diagonal extruded ribs transitioning deep blue, violet, magenta, coral and orange-red, plus only a few small clear glass cubes. Use humanist sans-serif typography, graphite labels, thin line icons, high-key studio light and subtle blue-violet bounce. No Microsoft logo, no Office logo, no third-party logo, no watermark, no QR code, no real identities, no old dates, no gibberish.
