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 single-page web app with an animated synthwave sunset scene. This should include:
1. A glowing gradient sun
2. Scanlines effect
3. An infinite neon grid that scrolls toward the viewer
4. A starfield
5. A reflected horizon (water reflection)

All in one self-contained index.html file with no external resources. Let me create this with HTML, CSS, and JavaScript all inline.

→ write /tmp/ws/index.html (10128 bytes)

Done! I've created `/tmp/ws/index.html` - a self-contained synthwave sunset animation featuring:

- **Glowing gradient sun** with yellow-to-pink-to-purple colors and horizontal scanlines
- **Starfield** with twinkling stars in the dark purple sky
- **Infinite scrolling neon grid** with perspective lines (magenta vertical, cyan horizontal) moving toward the viewer
- **Reflected horizon** with the sun and grid mirrored in a shimmering water surface below
- **CRT-style scanlines** overlay for that retro aesthetic
- **Vignette effect** for added atmosphere

All CSS and JavaScript are inline - no external dependencies. Open the file in a browser to see the animation!
