Design a monochrome interface built entirely from ONE hue: pick deep blue and derive everything: background (#10131a at 95% darkness), surfaces (85%), borders (70%), muted text (50%), primary text (15%), highlight (#5b7bd6). No second color anywhere; hierarchy comes from luminance steps, weight and scale. Imagery converted to the same single-hue duotone. Crisp geometric sans. The single CTA uses the brightest tone with dark text. Depth via tone, not shadows. Avoid: any second hue including grays with different undertones, colored status icons: translate everything into the scale. Build an original, complete composition around the actual business and its visitor task. Use the live demonstration as a visual reference, not a universal section template. Lead with specific objects, useful content and appropriate photography. Use supplied real project imagery; label fictional concepts and generated imagery honestly. Never invent clients, testimonials, awards, usage counts or results. Give every visible control a useful outcome and an accessible name. Use deliberate motion for spatial relationships and state changes; support keyboard, touch and prefers-reduced-motion. Verify desktop and mobile layouts, image loading, contrast and form states. Avoid generic AI slogans, rhetorical em dashes, arbitrary decorative badges and repetitive three-card sections.
