System prompt

This is a functional system error page (Cloudflare 522) for reveal.co, using a standard system-ui font stack for maximum clarity. The palette is utilitarian: white background, light grey status areas, and high-chroma status colors (green for success, red for error, blue for links). The layout is a simple, responsive grid with centered content. Key design constraints: avoid decorative elements, use a system font stack, keep status colors distinct for quick diagnosis, and maintain a clean, borderless aesthetic. The primary focus is communicating a connection failure clearly and providing actionable steps for both visitors and site owners.
