`/tmp/ws/index.html` is ready. Here's what it renders: - **Gradient sky** — deep purple/navy at top fading through magenta to orange-red at the horizon - **Twinkling starfield** — 350 stars with varying size, color tint, and per-star twinkle timing - **Glowing synthwave sun** — multi-layered radial glow, orange→pink gradient body, and the classic horizontal "slice" stripes that wobble gently - **Mountain silhouette** — jagged dark profile along the horizon - **Infinite neon grid** — perspective-projected grid with ~50 horizontal lines and 28 vertical lines scrolling toward the viewer, colored hot pink/magenta with depth-based alpha and thickness - **Water reflection** — dark mirrored surface with shimmering sun-reflection streaks - **CRT post-processing** — CSS scanline overlay + radial vignette (both `pointer-events: none`, no JS needed) Everything is self-contained: no external resources, no CDNs, runs fully sandboxed.

EVALUATION
Static-looking but well-rendered synthwave sunset with glowing sun, grid, mountains, and starfield; no visible input response, grid scroll not evident in stills.
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.
