This animated sunrise scene uses pure SVG with SMIL animations to cycle through a day-to-night transition. The sky gradient shifts from aliceblue to indigo, stars fade in and out, and a sun circle moves downward before resetting. Two landscape paths use linear gradients that darken in sync with the sky, creating a layered silhouette effect. The code leverages SVG’s `<animate>` and `<radialGradient>` elements to drive the 15-second loop without JavaScript libraries.
