# Design Brief: Vibrant Pop (with Soft & Friendly)

Full-bleed high-saturation brand backdrops, oversized bold display type, and high-contrast buttons, common across creator tools and consumer apps.

## Design Tokens

```css
:root {
  --background: #3b82e6;
  --surface: #ffffff;
  --foreground: #ffffff;
  --muted-foreground: #e8f1ff;
  --accent: #e07a6a;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #3B82E6 (~58%) · Surface #FFFFFF (~24%) · Text #FFFFFF (~8%) · Muted Text #E8F1FF (~5%) · Accent #E07A6A (~5%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: Full-Width Top Bar
- Theme & density: Dark · Balanced
- Border radius & elevation: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up
- Headline hook: Category Positioning Anchor
- Hero components: Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Vibrant Pop (Dark canvas, balanced density) featuring centered headline + cta layout and illustration / character art visuals.

## Avoid

- Muted corporate gray palettes
- Tiny low-contrast body text
- Overly formal enterprise tables

Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
