Create a flat vector illustration background for an energy simulation app, showing a modern suburban neighborhood in an African city. The scene should feature a contemporary single-story house as the focal point in the center-foreground, with a clean geometric design and flat roof suitable for solar panel installation. The house should have large windows, modern architectural lines, and earth-tone colors (warm browns, ochres, and terracotta). Surrounding the main house, include 3-4 additional homes in the background with varied architectural styles typical of modern African urban development - some with pitched roofs, others flat, in colors like cream, light brown, and soft orange. Include scattered palm trees, acacia trees, and tropical vegetation throughout the neighborhood. The background should show distant city buildings on the horizon - modern office buildings and residential towers in muted silhouettes. Include infrastructure elements like power lines, street lamps, and a paved road leading to the house. The illustration should use a warm color palette with earthy tones: sandy yellows, terracotta oranges, deep browns, and sage greens. The style should be clean, minimalist vector art with subtle gradients and flat design principles. No shadows or complex textures - just clean geometric shapes with clear line definition. Create two variants: DAY VERSION: Bright blue-white sky gradient, warm golden lighting, vibrant colors NIGHT VERSION: Deep blue-purple sky gradient, cooler lighting, muted colors with warm house interior lighting glowing through windows The composition should be wide (16:9 aspect ratio) with the main house positioned slightly left of center, leaving space on the right for UI overlays. Maintain a low horizon line to emphasize the sky area where sun, clouds, and weather animations will be placed." Technical Specifications: Style: Flat vector illustration, geometric shapes Color Palette: Warm earth tones, high contrast for UI overlay compatibility Resolution: Scalable vector format (SVG preferred) Composition: 16:9 landscape, main house left-of-center Elements: Minimal detail to allow overlay animations Lighting: Natural directional lighting that can transition between day/night Cultural Context: Modern African suburban architecture and vegetation This background will serve as the foundation for all dynamic elements including solar panel overlays, sun movement animations, weather effects, and energy flow visualizations.
