Minimalist Abstract Landscape of Layered Hills

minimal panoramic vector landscape of layered rolling hills, smooth overlapping wave-like bands of green terrain stretching horizontally across the frame, darker forest-green hills in the foreground and progressively lighter lime-green hills in the distance, subtle dotted halftone grain texture across each hill layer, clean white empty sky above, simple flat illustration, crisp edges, no trees, no buildings, no people, no text, calm abstract nature background
