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 an animated synthwave sunset scene in a single HTML file. This should include:
1. A glowing gradient sun with scanlines setting
2. An infinite neon grid that scrolls toward the viewer (classic 80s perspective grid)
3. A starfield background
4. A reflected horizon effect

Let me create this with CSS animations and JavaScript for the dynamic effects. I'll use HTML5 Canvas for the rendering to achieve smooth animations.

Key elements to implement:
- Gradient sun with horizontal scanline stripes
- Perspective grid that animates/scrolls
- Stars twinkling in the background
- Sun reflection on the "water" surface below horizon
- Synthwave color palette (purples, pinks, oranges, cyans)

Let me write this as a self-contained HTML file.

→ write index.html (12685 bytes)

The file has been created successfully. Let me summarize what I've built for the user.

Created `index.html` with a complete animated synthwave sunset featuring: - **Glowing gradient sun** - Yellow→orange→red gradient with horizontal scanline stripes cut across it - **Sun glow halo** - Radial glow effect around the sun - **Infinite scrolling neon grid** - Perspective grid on the ground plane with vertical lines converging to the horizon and horizontal lines that animate toward the viewer - **Starfield** - 200 twinkling stars in the sky with subtle glow effects - **Reflected horizon** - Wavy water-like reflection of the sun below the horizon line with shimmer effects - **Silhouette mountains** - Animated mountain range along the horizon - **Scanline overlay** - Subtle CRT-style scanlines across the entire scene - **Vignette** - Dark corners for atmospheric depth - **Purple/pink color palette** - Classic synthwave aesthetic with magenta grid lines and purple sky gradients All animations run via `requestAnimationFrame` with smooth 60fps rendering. Open `index.html` in any browser to view.
