A wide horizontal vector-style space background showing only open space (full sky view), with a deep dark green gradient as the base. No land, no ground, no horizon — only space. The background should use smooth gradients of dark green, emerald green, and deep teal-green tones. Keep the palette strictly within green shades — no blue dominance, no yellow, no warm colors. Include 3 to 4 distant planets, each different in size and design: - One slightly larger planet placed near an edge (partially visible) - Other planets smaller and placed far apart to create depth All planets should follow a green-based palette (emerald, dark green, subtle teal-green highlights) with smooth vector gradients and soft glow. No textures, no realism. Add very few tiny soft glowing stars, minimal and widely spaced. Keep large empty areas for UI and smooth panning. Lighting should be soft ambient glow, with subtle highlights on planets and smooth shading. No harsh contrast. Edges must be soft and blendable so multiple images can merge seamlessly into a wide panning background. Style: flat vector, smooth gradients, minimal, modern game UI Color palette: dark green, emerald, deep teal-green (strictly green tones) Composition: spacious, mostly empty, balanced Aspect ratio: ultra wide (3:1 or 4:1), fixed height Quality: ultra clean, no noise, no grain, no sharp edges
