# Design Brief: Precision Swiss Grid (with Soft & Friendly)

Exposed 1px hairline grid rules with intersection crosshairs, modular bento cards, and strict geometric alignment with modern engineering craft.

## Design Tokens

```css
:root {
  --background: #f7f6fa;
  --surface: #ffffff;
  --foreground: #17171c;
  --muted-foreground: #66656d;
  --accent: #4238c9;
  --radius: 16px;
  --font-heading: "sans-serif", ui-sans-serif, system-ui, sans-serif;
  --font-body: "sans-serif", ui-sans-serif, system-ui, sans-serif;
}
```

Color area ratio: Background #F7F6FA (~76%) · Surface #FFFFFF (~4%) · Text #17171C (~12%) · Muted Text #66656D (~6%) · Accent #4238C9 (~2%). 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; no drop shadows—separate layers with hairline borders and whitespace
- Primary visual medium: Illustration / Character Art
- Conversion CTA: Start Free / Sign Up
- Headline hook: Target Audience Callout
- Hero components: Custom Illustration, Floating Multi-Cards
- Spatial layout notes: Split Copy & Visual hero structure paired with start free / sign up CTA and no explicit trust bar.
- Visual summary: Precision Swiss Grid (Light canvas, balanced density) featuring split copy & visual layout and illustration / character art visuals.

## Avoid

- Soft organic blobs
- Misaligned freeform floating elements
- Heavy drop shadows that obscure grid hairlines

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.
