# Design Brief: Precision Swiss Grid (with Minimal Monochrome)

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

## Design Tokens

```css
:root {
  --background: #f4f5f7;
  --surface: #ffffff;
  --foreground: #0f172a;
  --muted-foreground: #64748b;
  --accent: #0f172a;
  --radius: 8px;
  --font-heading: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-body: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}
```

Color area ratio: Background #F4F5F7 (~45%) · Surface #FFFFFF (~40%) · Text #0F172A (~8%) · Muted Text #64748B (~5%) · Accent #0F172A (~2%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Layout & Conversion Structure

- Hero layout: Headline Over Large Product Shot
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Medium Radius; use elevation shadows to separate layers
- Primary visual medium: Interactive Hero Demo / Tool
- Conversion CTA: Direct Input / Instant Try
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Code & Terminal, Interactive Hero Tool
- Spatial layout notes: Headline Over Large Product Shot hero structure paired with direct input / instant try CTA and no explicit trust bar.
- Visual summary: Precision Swiss Grid (Light canvas, balanced density) featuring headline over large product shot layout and interactive hero demo / tool 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.
