# Design Brief: Neo-Brutalism (with Vibrant Pop)

Bold black strokes, hard offset shadows, and high-saturation color blocks.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #fff1f9;
  --foreground: #101018;
  --muted-foreground: #454545;
  --accent: #f509a3;
  --radius: 9999px;
  --font-heading: "Arial Black", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Noto Sans JP", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~79%) · Surface #FFF1F9 (~9%) · Text #101018 (~4%) · Muted Text #454545 (~2%) · Accent #F509A3 (~6%). 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: Minimal Logo + Action
- Theme & density: Light · Airy
- Border radius & elevation: Pill; use elevation shadows to separate layers
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Start Free / Sign Up
- Headline hook: Brand Manifesto & Curiosity
- 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: Neo-Brutalism (Light canvas, airy density) featuring centered headline + cta layout and pure typography & geometry visuals.

## Avoid

- Soft blurred shadows
- Low-contrast gray-on-gray borders
- Subtle translucent glassmorphism

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.
