# Sauci Design System

A boutique, premium design framework for the Sauci couples relationship app.

## Brand Identity

**Aesthetic:** Premium couples app with a warm, sophisticated feel. Think modern wellness meets connection - supportive but not clinical, premium but accessible, personal but playful.

**Mood:** Warm, supportive, confident, inviting, growth-oriented

**Key Principles:**

- Dark, velvety backgrounds with subtle gradient atmosphere
- Solid, high-contrast surfaces (no glass or blur effects)
- Primary gradient (rose → purple) as the core brand signature
- Gold reserved for premium/dares features only
- Soft glows and shadows for depth, not transparency

// Usage
const styles = {
  backgroundColor: theme.colors.background,

};
