The complete synthwave sunset animation is now saved as `/tmp/ws/synthwave-sunset.html`. Here's what it includes: 1. **Glowing Gradient Sun**: A pulsating, glowing sun with radial gradient and dynamic glow effects 2. **Scrolling Neon Grid**: Infinite scrolling grid with cyan and magenta neon patterns 3. **Starfield**: Randomly placed twinkling stars with subtle movement 4. **Reflected Horizon**: A wavy, reflective horizon with gradient fade 5. **Scanlines**: Animated scanlines effect that pulses in intensity 6. **Synthwave Aesthetic**: All elements combined with a retro-futuristic vibe The design uses CSS variables for dynamic effects, CSS animations for all movements, and pure HTML/CSS for the complete visual experience. Open it in a browser to see the full animation.

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.
