Voice & Don'ts
Tone Direct, informative, and technically precise. Headlines Large, light-weight, and declarative. CTAs Informational links rather than call-to-action buttons. Don't use decorative fonts — screenshot shows a highly legible system sans-serif stack. Don't add complex shadows or depth — screenshot shows a flat design with only a subtle gradient background. Don't use a dark color scheme — screenshot shows a bright white background with dark gray text. Don't hide the error code — screenshot shows it prominently in a small, distinct badge next to the headline. Don't use multiple accent colors — screenshot uses a limited palette where red and green are strictly for status icons. Don't create a cluttered layout — screenshot shows generous whitespace and a clear visual hierarchy with a large title. Avoid: Jargon without explanation Avoid: Playful or informal language Avoid: Dense, unbroken paragraphs of text Avoid: Vague instructions Avoid: Overuse of bold or strong emphasis

System prompt
This is a utilitarian error page design focused on clarity and information delivery. The palette is neutral, using #FFFFFF for background and #404040 for primary ink, with semantic green and red for status. Typography is a system sans-serif stack, with a very light 60px display weight for the main headline. The layout is a centered container that switches from a 3-column status diagram to a vertical stack on mobile. Critical donts: don't use decorative fonts, don't add complex shadows, and don't hide the specific error code. The design prioritizes immediate recognition of a system failure and provides clear, actionable instructions.
