Generate an SVG scene in a low-poly style: a tranquil landscape with rolling hills, a distant mountain range, and a simple sun. The image should be constructed entirely from flat, polygonal facets—triangles and quadrilaterals—without gradients or textures. Use crisp vector paths for each polygon; ensure all edges meet with perfect alignment to avoid overlap gaps. Choose a restrained color palette of 6–8 solid fills: deep forest greens, lime, teal, cobalt, peach, and sand, with light source assumed from the top-right to guide facet shading via color blocks rather than shading effects. Objects should be stylized and faceted: hills as overlapped triangles, a lake as a flat blue polygon, trees as simplified stacked prisms, and the sun as a glowing polygon. Keep strokes minimal or none; if strokes are used, keep them consistent and subtle. Group related polygons into logical layers (background sky, midground terrain, foreground elements) and label with clear IDs for an image generation pipeline. The result should render crisply at common viewports and scale cleanly.

The image shows a painting of a lake surrounded by lush green hills and trees, with a bright blue sky and fluffy white clouds in the background.
