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.

Let me create a synthwave sunset scene with all the requested elements. I'll build it in a single index.html file with canvas-based rendering for the grid, sun, stars, and reflections.

Created `/workspace/index.html` — a self-contained synthwave sunset scene rendered on a single canvas. It includes: - **Glowing gradient sun** with yellow→orange→pink→magenta vertical gradient, a soft outer glow, a crisp rim, and dark **scanline gaps** that widen toward the bottom of the disc. - **Infinite neon grid** with perspective horizontal lines scrolling toward the viewer (accelerating spacing near camera) and cyan vertical lines converging to a vanishing point on the horizon. - **Starfield** twinkling above the horizon, with randomized phases and sizes. - **Reflected horizon**: a mirrored, squashed sun glow plus water-like shimmer ellipse fading into the dark ground, with a warm horizon band. - Layered **sunset sky gradient** (deep purple → magenta → hot pink → amber) with a top vignette. Everything is responsive (handles resize + DPR scaling) and runs in a `requestAnimationFrame` loop with no external resources.

EVALUATION

3/5 working

Static synthwave sun/grid scene rendered nicely but shows no grid scroll animation or reaction to any input tested.

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.
