An animated sunset scene shows the sun descending toward the sea, with the sky cycling through warm and dark color phases. The SVG uses `radialGradient` defs for both sky and sea, while `<animate>` tags on the sun's `cy` and `fill` attributes, along with similar animations on mountain, sand, and sea paths, create the looping 15-second transition. The landscape layers render as vector paths with fill colors that morph between light and dark states.
