Prompt for this run

Build an animated synthwave landscape on a full-screen canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Draw a glowing gradient sun broken by horizontal scanline bands, a starfield, and a perspective neon grid extending from the foreground to a horizon. - Animate the grid toward the viewer to suggest forward travel. Move the sun slowly down toward the horizon while keeping the composition visible. - Below the horizon, include a stylized reflection of the sun's colors on the ground plane, visually distinct from a second sun in the sky. - Use a loop of 10 to 20 seconds that repeats without a distracting reset jump. Provide Pause/Resume and Restart controls. - Use procedural drawing and colors only. Fit the canvas to the viewport; choose the palette and decorative details freely. Verify: Sample several moments to inspect grid travel, sun movement, and the reflected colors below the horizon. Pause and resume to check animation control, then use Restart and compare the starting composition.

The scene looks great. Let me sample a few more moments to verify animation: grid travel, sun movement, reflection.
