# 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: #d4e6f4;
  --surface: #ffffff;
  --foreground: #1b3a8c;
  --muted-foreground: #6a7eae;
  --accent: #3d6ad6;
  --radius: 0px;
  --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 #D4E6F4 (~55%) · Surface #FFFFFF (~14%) · Text #1B3A8C (~8%) · Muted Text #6A7EAE (~8%) · Accent #3D6AD6 (~15%). 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: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Sharp; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up
- Headline hook: Category Positioning Anchor
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Gradient Glow (Light canvas, airy density) featuring split copy & visual layout and photography / live video visuals.

## Avoid

- Muddy low-contrast text over gradients
- Overuse of full-screen rainbow backgrounds
- 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.
