# Design Brief: Hand-Drawn & Sketch

Handwritten display accents, doodle annotations, and sketch-style illustrations.

## Design Tokens

```css
:root {
  --background: #1a1a1a;
  --surface: #111111;
  --foreground: #ffffff;
  --muted-foreground: #c8c8c8;
  --accent: #f5c518;
  --radius: 9999px;
  --font-heading: "Nanum Pen Script", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Pretendard", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #1A1A1A (~62%) · Surface #111111 (~12%) · Text #FFFFFF (~10%) · Muted Text #C8C8C8 (~8%) · Accent #F5C518 (~8%). 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 · Airy
- Border radius & elevation: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Start Free / Sign Up
- Headline hook: Outcome & Speed Promise
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Hand-Drawn & Sketch (Dark canvas, airy density) featuring centered headline + cta layout and pure typography & geometry visuals.

## Avoid

- Rigid corporate stock photography
- Heavy 3D metallic renders
- Overly dense enterprise dashboards

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.
