Preview full AI design brief (includes :root CSS variables & layout rules)Style tokens only; never copy brand names, logos, copy, or images
# Design Brief: Soft & Friendly
Warm low-saturation pastels, generous rounded corners, and approachable illustrations.
## Design Tokens
```css
:root {
--background: #f8f9fb;
--surface: #ffffff;
--foreground: #25252b;
--muted-foreground: #77777f;
--accent: #e91e50;
--radius: 8px;
--font-heading: "Nunito Sans", ui-sans-serif, system-ui, sans-serif;
--font-body: "Nunito Sans", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #F8F9FB (~76%) · Surface #FFFFFF (~8%) · Text #25252B (~7%) · Muted Text #77777F (~5%) · Accent #E91E50 (~4%). 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: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Start Free / Sign Up · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Pain Relief & Replacement
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and stacked avatars & testimonials.
- Visual summary: Soft & Friendly (Light canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component visuals.
## Avoid
- Harsh pure-black backgrounds
- Sharp 0px corners
- Cold technical jargon in hero copy
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.
