# 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: #168fe5;
  --surface: #ffffff;
  --foreground: #172b4d;
  --muted-foreground: #6687a7;
  --accent: #ff5d8f;
  --radius: 4px;
  --font-heading: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #168FE5 (~57%) · Surface #FFFFFF (~10%) · Text #172B4D (~14%) · Muted Text #6687A7 (~8%) · Accent #FF5D8F (~11%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

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.
