System prompt

A developer-focused SaaS platform for building internal tools. The design uses a dark mode palette with warm, muted grays (#151515, #E9EBDF) and a cool blue accent (#518DD2). Typography features a clean grotesque-sans for display and a humanist-sans for body text, with a heavy emphasis on large, thin-weight headlines. The layout is centered and spacious, with generous padding. Critical don'ts: never use high-saturation neon colors, avoid decorative serifs for headlines, and don't use sharp 90-degree corners for main UI containers. The tone is direct, technical, and confident.
