# Design Brief: 3D Tactile (with Soft & Friendly)

Rendered 3D objects, soft studio lighting, and tactile material depth.

## Design Tokens

```css
:root {
  --background: #f8fcff;
  --surface: #ffffff;
  --foreground: #252a34;
  --muted-foreground: #65717e;
  --accent: #4778f4;
  --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 #F8FCFF (~69%) · Surface #FFFFFF (~10%) · Text #252A34 (~8%) · Muted Text #65717E (~5%) · Accent #4778F4 (~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: Minimal Logo + Action
- Theme & density: Light · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: 3D Render / Tactile Object
- Conversion CTA: Download App / Install Extension
- Headline hook: Direct Action Command
- Hero components: Large Hero Product Shot
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and no explicit trust bar.
- Visual summary: 3D Tactile (Light canvas, balanced density) featuring split copy & visual layout and 3d render / tactile object visuals.

## Avoid

- Flat unstyled wireframes
- Cluttered text walls competing with the 3D focal point

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.
