# Design Brief: Hand-Drawn & Sketch (with Dark Developer)

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

## Design Tokens

```css
:root {
  --background: #141414;
  --surface: #390e3b;
  --foreground: #f2f5d4;
  --muted-foreground: #777b61;
  --accent: #ffcc43;
  --radius: 9999px;
  --font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #141414 (~71%) · Surface #390E3B (~13%) · Text #F2F5D4 (~3%) · Muted Text #777B61 (~5%) · Accent #FFCC43 (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Full-Bleed Canvas / Video / 3D
- Navigation: Full-Width Top Bar

- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up
- Headline hook: Pain Relief & Replacement
- Hero components: Custom Illustration
- Spatial layout notes: Full-Bleed Canvas / Video / 3D hero structure paired with start free / sign up CTA and no explicit trust bar.

## 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.
