# Design Brief: Vibrant Pop

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: #a0104a;
  --surface: #c9b8a4;
  --foreground: #ffffff;
  --muted-foreground: #8a7a6a;
  --accent: #e84b8a;
  --radius: 16px;
  --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 #A0104A (~42%) · Surface #C9B8A4 (~22%) · Text #FFFFFF (~18%) · Muted Text #8A7A6A (~10%) · Accent #E84B8A (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Split Copy & Visual
- Navigation: No Explicit Nav
- Theme & density: Dark · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up
- Headline hook: Outcome & Speed Promise
- Hero components: Large Hero Product Shot
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Vibrant Pop (Dark canvas, balanced density) featuring split copy & visual layout and photography / live video 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.
