Perfect! I've created a stunning animated synthwave sunset in a single HTML file. Here's what you'll see: **Features:** - 🌅 **Glowing gradient sun** with radial gradients from gold to magenta, with a soft glow effect - 📡 **Horizontal scanlines** across the sun for that retro CRT look - 🌌 **Animated starfield** with twinkling stars in the dark sky - 🟫 **Infinite neon grid** that scrolls toward the viewer with perspective projection - 💫 **Reflected horizon** with subtle grid reflection below the horizon line - ⚡ **Neon horizon line** with glow effect - 📺 **Scanline overlay** across the entire scene - 🎨 **Vignette effect** for cinematic framing **Technical details:** - Pure HTML5 Canvas rendering - Smooth 60fps animation using requestAnimationFrame - Fully self-contained (no external dependencies) - Responsive design that fills the viewport - Perspective-correct grid scrolling - Dynamic alpha blending for depth The animation runs continuously with the grid scrolling infinitely toward the viewer, creating that classic synthwave aesthetic. Open the file in any modern browser to see the full effect!

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
