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: #ffffff;
--surface: #1b1e2a;
--foreground: #1b1e2a;
--muted-foreground: #3c3c3c;
--accent: #f15152;
--radius: 9999px;
--font-heading: "Noto Sans", ui-sans-serif, system-ui, sans-serif;
--font-body: "Noto Sans", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~75%) · Surface #1B1E2A (~11%) · Text #1B1E2A (~7%) · Muted Text #3C3C3C (~4%) · Accent #F15152 (~3%). 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: Pill; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Outcome & Speed Promise
- Hero components: Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and user count, rating, or key metrics.
- Visual summary: Soft & Friendly (Light canvas, airy density) featuring split copy & visual layout and pure typography & geometry 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.
