# Design Brief: Soft & Friendly

Warm low-saturation pastels, generous rounded corners, and approachable illustrations.

## Design Tokens

```css
:root {
  --background: #f7f8fa;
  --surface: #ffffff;
  --foreground: #1f2937;
  --muted-foreground: #6b7280;
  --accent: #111827;
  --radius: 8px;
  --font-heading: "PingFang SC", ui-sans-serif, system-ui, sans-serif;
  --font-body: "PingFang SC", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F7F8FA (~42%) · Surface #FFFFFF (~34%) · Text #1F2937 (~12%) · Muted Text #6B7280 (~7%) · Accent #111827 (~5%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Hero Bento Grid
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Medium Radius; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Photography / Live Video
- Conversion CTA: Start Free / Sign Up
- Headline hook: Category Positioning Anchor
- Spatial layout notes: Hero Bento Grid hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Soft & Friendly (Light canvas, balanced density) featuring hero bento grid layout and photography / live video 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.
