# Design Brief: Enterprise Clean

Trustworthy blue-anchored palette, structured grids, and prominent customer logo walls.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f3f8fc;
  --foreground: #333333;
  --muted-foreground: #8a8a8a;
  --accent: #1e88e5;
  --radius: 4px;
  --font-heading: "Microsoft YaHei", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Microsoft YaHei", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~62%) · Surface #F3F8FC (~16%) · Text #333333 (~8%) · Muted Text #8A8A8A (~6%) · Accent #1E88E5 (~8%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Conversion CTA: Direct Input / Instant Try · Trust bar uses Customer / Press Logo Strip
- Headline hook: Category Positioning Anchor
- Hero components: Centered Prompt / Input, Customer Logo Wall

## Avoid

- Experimental navigation patterns
- Low-legibility decorative fonts
- Visual novelty that obscures the value proposition

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.
