Present one single mobile app icon for the App Type as a real App Store or Google Play icon, centered on a square 1:1 canvas. Use an iOS-style rounded-square shape occupying about 70 percent of the canvas width, with smooth corners and a soft, subtle drop shadow on a plain very light neutral background. Inside the icon, translate the Icon Concept into one bold, instantly readable symbol with comfortable padding, a strong silhouette, crisp edges and smart negative space. Render it in the Style using the Color Palette, with strong contrast between the symbol and its background. Keep the design simple and iconographic rather than illustrative, with no detailed scene, extra objects, text, letters, sparkles, glow or thin hairlines. Show no device, hands, mockup or additional icons. Make it feel original and avoid resemblance to existing app icons, logos or mascots. No watermarks.
Use these details:
App Type: "Interior Design App"
Icon Concept: "A simple sofa silhouette inside a house outline"
Style: "Flat icon design with clean geometric shapes"
Color Palette: "Sage green and terracotta"
