A minimalist SVG scene depicting a sky gradient, rendered via React and raw SVG elements. A rectangular backdrop uses a `radialGradient` with animated `stop-color` transitions that cycle from aliceblue to indigo over 15 seconds and repeat indefinitely, creating a subtle color-shifting effect. The second gradient stop remains a static steelblue. The example demonstrates how CSS and JavaScript can drive SVG animations without external libraries, relying solely on native SVG `<animate>` elements and inline styling to produce a dynamic, full-viewport visual.
