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. The request includes: 1. A glowing gradient sun 2. Scanlines effect 3. Sunset (sun setting down) 4. Infinite neon grid that scrolls toward the viewer 5. Starfield background 6. Reflected horizon This should be a single HTML file with inline CSS and JavaScript, no external resources. I'll use HTML5 Canvas for the animations as it's the best approach for this kind of visual effect. Let me plan the structure: 1. **HTML Structure**: Basic HTML5 boilerplate with a full-screen canvas 2. **CSS**: Full screen styles, maybe some scanline overlay effects 3. **JavaScript**: - Canvas setup and resize handling - Starfield (random stars with twinkling) - Sun (gradient circle that moves down) - Grid (perspective grid scrolling toward viewer) - Reflection effect (mirroring the grid and sun) - Scanlines overlay (CSS-based) Key visual elements: - Dark background (deep purple/black) - Neon colors (pink, cyan, purple) - Perspective grid that creates depth - Sun with glow effect - Retro scanline aesthetic Let me code this step by step: 1. Full-screen canvas 2. Star generation (random positions, varying sizes/brightness) 3. Sun gradient with glow 4. Grid with perspective (3D projection) 5. Grid scrolling animation 6. Reflection for the horizon 7. Scanline overlay via CSS The grid needs to be in perspective - lines converging toward a vanishing point. For a classic synthwave look, the grid should be: - Horizontal lines that move down (creating scroll effect) - Vertical lines that converge to center - Neon cyan/pink colors - Below the horizon line I'll use a 3D-to-2D projection for the grid to create the perspective effect. The grid "scrolls" by offsetting the Z coordinate over time. Let me write the code:

EVALUATION
Static sun with scanlines and starfield, but no neon grid, no horizon reflection, and no animation or input response.
Vision grade · anthropic/claude-sonnet-5
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.
