A looping SVG animation depicts a sunrise and sunset over a stylized landscape. A radial gradient sky shifts from aliceblue to indigo and back, while the sun’s vertical position oscillates between the sky and the horizon. Two layered path-based landmasses use linear gradients that synchronize with the same 15-second color cycle, creating a seamless day-night transition. The piece relies solely on native SVG elements, including `<animate>`, `<radialGradient>`, and `<linearGradient>`, with no external JavaScript libraries.
