# Design Brief: Dark Developer (with Gradient Glow)

Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.

## Design Tokens

```css
:root {
  --background: #000000;
  --surface: #202020;
  --foreground: #ffffff;
  --muted-foreground: #a1a1aa;
  --accent: #ffffff;
  --radius: 9999px;
  --font-heading: "Pretendard Variable", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Pretendard Variable", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #000000 (~69%) · Surface #202020 (~17%) · Text #FFFFFF (~6%) · Muted Text #A1A1AA (~4%) · Accent #FFFFFF (~4%). 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: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Download App / Install Extension · Trust bar uses Live Generated Output Showcase
- Headline hook: Outcome & Speed Promise
- Hero components: Floating Multi-Cards, Metrics Strip
- Spatial layout notes: 상단에 브랜드와 탐색 메뉴를 두고, 중앙에 공지·제목·설명·스토어 버튼을 쌓은 뒤 하단에 뉴스 카드를 2열로 배치했습니다.
- Visual summary: 검은 바탕에 은은한 회색 광원을 깔고 Pretendard 제목과 흰색 캡슐형 스토어 버튼을 중앙 정렬했으며, 아래쪽에 실시간 뉴스 카드를 배치했습니다.

## Avoid

- Warm pastel backgrounds
- Playful cartoon illustrations
- Oversized pill buttons everywhere

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.
