System prompt

Design a high-trust, institutional fintech platform. Use a stark white background with deep black text for maximum readability. The primary brand color is a vibrant, high-chroma blue used exclusively for interactive elements like buttons and links. Typography should be clean and geometric, using a sans-serif for headlines and body text, with tight letter-spacing for large display sizes to maintain a modern, technical feel. Avoid any dark mode, playful aesthetics, or multi-color gradients. Layouts must be centered, spacious, and strictly grid-aligned to convey stability and reliability. Components like buttons should be pill-shaped with high contrast. Critical donts: do not use dark backgrounds; do not use decorative serif fonts; do not use more than one primary accent color.
