# 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: #f8f5fa;
--foreground: #171717;
--muted-foreground: #737373;
--accent: #963de7;
--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 (~69%) · Surface #F8F5FA (~10%) · Text #171717 (~6%) · Muted Text #737373 (~10%) · Accent #963DE7 (~5%). 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 · Balanced
- Border radius & elevation: Large Radius; use elevation shadows to separate layers
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Category Positioning Anchor
- Hero components: Centered Prompt / Input, Interactive Hero Tool
- Spatial layout notes: Split Copy & Visual hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Gradient Glow (Light canvas, balanced density) featuring split copy & visual layout and pure typography & geometry 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.
