- Don't use subtle, muted accents — screenshot shows a single, highly saturated electric yellow accent (#F1F252).
- Don't use sharp, square corners — screenshot shows large, pill-shaped radii (24px/32px) on buttons and cards.
- Don't use complex gradients — screenshot shows flat color fills and simple photographic backgrounds.
- Don't use delicate, thin borders — screenshot shows prominent, 1px solid dark borders on interactive elements.

## System Prompt (paste into AI agent)

```
GoCardless is a premium B2B fintech platform for automated payments. The design DNA features a warm off-white background (#EFECE7) with deep charcoal ink (#1C1B18), punctuated by a high-chroma electric yellow accent (#F1F252). Typography relies heavily on a bold, geometric sans-serif (Haffer) for display, paired with a highly legible humanist sans-serif for body copy. Key critical constraints: 1) Never use a dark mode or purely black backgrounds for content sections. 2) Always use a heavy font-weight (700) for major headlines to maintain the brand's bold presence. 3) Strictly avoid using more than one high-chroma color; the electric yellow must be used sparingly for primary CTAs only.
