This animated SVG landscape depicts a stylized sunrise and sunset cycle over layered mountain silhouettes. The sky backdrop and terrain use radial and linear gradients, while a circle representing the sun animates its vertical position. SVG `<animate>` elements continuously shift gradient stop colors between aliceblue and steelblue, and the sun’s `cy` attribute moves from 250px to 350px and back, simulating a day-night loop. The scene combines three distinct path shapes filled with gradient definitions to create depth.
