# Design Brief: Gradient Glow

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

## Design Tokens

```css
:root {
  --background: #062a2e;
  --surface: #0d3d42;
  --foreground: #ffffff;
  --muted-foreground: #b7e6e8;
  --accent: #f2d23a;
  --radius: 4px;
  --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 #062A2E (~42%) · Surface #0D3D42 (~18%) · Text #FFFFFF (~16%) · Muted Text #B7E6E8 (~14%) · Accent #F2D23A (~10%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Centered Headline + CTA
- Navigation: No Explicit Nav
- Theme & density: Dark · Balanced
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up
- Headline hook: Pain Relief & Replacement
- Hero components: Custom Illustration
- Spatial layout notes: Centered Headline + CTA hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Gradient Glow (Dark canvas, balanced density) featuring centered headline + cta layout and illustration / character art 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.
