# Design Brief: Gradient Glow (with Soft & Friendly)

Luminous radial glows and translucent glass panels, widely used across modern AI products.

## Design Tokens

```css
:root {
  --background: #ffffff;
  --surface: #f5f7ff;
  --foreground: #30394b;
  --muted-foreground: #737b89;
  --accent: #3565e8;
  --radius: 16px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #FFFFFF (~81%) · Surface #F5F7FF (~7%) · Text #30394B (~5%) · Muted Text #737B89 (~4%) · Accent #3565E8 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

- Cluttered dense tables in the hero

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.
