- **hero:** Large, serif-led text block paired with a descriptive paragraph and dual CTAs.

## Do's and Don'ts

**Don't:**
- Don't use a dark mode theme — the screenshot shows a consistently light, bright background.
- Don't use aggressive gradients — the screenshot shows solid colors and subtle tints.
- Don't use heavy drop shadows — the screenshot shows very flat, minimal elevation.
- Don't use neon or high-chroma accent colors — the screenshot uses a single deep, natural green.
- Don't use highly decorative or script fonts — the screenshot uses clean, legible typefaces.
- Don't use cluttered navigation with too many items — the screenshot shows a streamlined, spacious top bar.

## System Prompt (paste into AI agent)

```
Cartesia is an AI startup positioning itself as a provider of foundational research and tools for human-like voice agents. The design reflects a 'research lab meets enterprise product' identity. The palette is anchored by a near-white background (#FAFAFA) and deep charcoal ink (#1A1A1A), with a signature natural green (#1B7A3D) used for accents and highlights. Typography contrasts a transitional serif for display text (PP Kyoto) with a clean humanist sans (ABC Diatype) for body and UI. Critical design constraints: avoid dark mode entirely, maintain generous whitespace, and use only subtle, solid-color borders or tints rather than heavy shadows or complex gradients.
