Create an animated synthwave sunset: a glowing gradient sun with scanlines setting over an infinite neon grid that scrolls toward the viewer, with a starfield and a reflected horizon.

The user wants me to create a synthwave sunset animation as a single HTML file. This is a classic synthwave/vaporwave aesthetic with:

1. A glowing gradient sun setting on the horizon
2. Scanlines overlay on the sun
3. An infinite neon grid that scrolls toward the viewer
4. A starfield in the sky
5. A reflected horizon

Let me create this as a self-contained index.html with all CSS and JS inline.

I'll use canvas for the animation since it involves complex rendering like grids, reflections, and particle effects.

Let me plan the components:
1. **Starfield**: Random stars twinkling in the upper portion
2. **Sun**: Large circle with gradient (pink/purple/orange) with horizontal scanlines cut through it


3. **Sky gradient**: Deep purple/dark blue gradient from top
4. **Grid**: Perspective grid on the ground plane that scrolls toward viewer
5. **Horizon reflection**: Mirror effect below horizon line
6. **Mountains/city silhouette**: Optional but adds to the aesthetic

I'll build this with canvas for performance and smooth animation.

The file is created. Let me verify it's there and looks good.

Done! `/workspace/index.html` is ready — a fully self-contained synthwave sunset with: - **Starfield** — twinkling stars across the dark upper sky - **Gradient sun** — yellow → hot pink → deep magenta with animated horizontal scanlines slicing through it - **Mountain silhouette** — undulating horizon line that dips at center to frame the sun - **Horizon glow** — warm radial light bloom where sun meets horizon - **Infinite neon grid** — purple perspective grid with a vanishing point, lines scrolling toward the viewer - **Sun reflection** — soft color wash reflected onto the grid plane - **CRT scanline overlay** — subtle full-screen scanlines for that retro feel All CSS and JS inline, zero external dependencies. Open `index.html` in any browser to watch the animation.
