Created a self-contained `index.html` with an animated synthwave sunset: - **Glowing gradient sun** with magenta, orange, and cyan hues + scanlines - **Infinite neon grid** scrolling toward the viewer (cyan and magenta) - **Starfield** with twinkling stars moving downward - **Reflected horizon** with gradient fade - **No external dependencies** (pure HTML5 Canvas) Open the file in a browser to see the animation. Adjust the window size to test responsiveness.
