A scenic sunrise and sunset animation is rendered entirely as an SVG. It depicts a circular sun moving vertically against a dynamically changing sky and layered landscape, with colors transitioning to suggest a day-night cycle. The code uses native SVG elements like `radialGradient`, `linearGradient`, and `path`, along with the SVG `<animate>` API to continuously shift gradient stops and the sun’s `cy` attribute. No external JavaScript libraries are employed; rendering is purely through static SVG markup.
