# Design Brief: Soft & Friendly (with Enterprise Clean)
Warm low-saturation pastels, generous rounded corners, and approachable illustrations.
## Design Tokens
```css
:root {
--background: #ffffff;
--surface: #e0e1e2;
--foreground: #171717;
--muted-foreground: #767676;
--accent: #c52a1d;
--radius: 4px;
--font-heading: "didact", ui-sans-serif, system-ui, sans-serif;
--font-body: "Lato", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #FFFFFF (~80%) · Surface #E0E1E2 (~7%) · Text #171717 (~6%) · Muted Text #767676 (~4%) · Accent #C52A1D (~3%). 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: Full-Width Top Bar
- Theme & density: Light · Airy
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Pure Typography & Geometry
- Conversion CTA: Start Free / Sign Up · Trust bar uses User Count, Rating, or Key Metrics
- Headline hook: Brand Manifesto & Curiosity
- Hero components: Metrics Strip
- Spatial layout notes: Centered Headline + CTA 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 centered headline + cta 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.
