Design Language

Blueprint Technical is the visual language of architectural and engineering drawings. Everything on screen looks like it was plotted on drafting paper: white and cyan lines on a deep blue background, faint grid squares, dimension annotations with terminal ticks, and monospace type that could have come off a plotter. The aesthetic is precise, legible, and unmistakably technical.

This is not a "dark mode theme with blue accents." The grid-paper background is the identity. Without the grid, you lose the blueprint. Every layout decision should reinforce the feeling that the user is looking at a technical drawing, not a marketing page.

Design Skill

Apply this design skill to make a product interface look like an architectural blueprint: white and cyan lines on deep blue, with a visible grid background, monospace headings, and technical drawing decorations.

### Step 1: Load the font

```html
<link href="https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@300;400;500;600;700&display=swap" rel="stylesheet">
```

### Step 2: Set CSS custom properties

```css
:root {
  --bp-deep: #1B2838;
  --bp-surface: #1E3248;
  --bp-elevated: #243B52;
  --bp-grid: #2A4A6B;
  --bp-line: rgba(120, 180, 220, 0.3);
  --bp-line-strong: rgba(120, 180, 220, 0.5);
  --bp-accent: #4FC3F7;
  --bp-accent-hover: #81D4FA;
  --bp-accent-dim: rgba(79, 195, 247, 0.15);
  --bp-text: #FFFFFF;
  --bp-text-secondary: #B8D4E8;
  --bp-text-muted: #6B8FAD;
  --bp-text-dim: #3E6380;
  --bp-danger: #EF5350;
  --bp-success: #66BB6A;
  --bp-warning: #FFA726;
  --font-heading: 'JetBrains Mono', 'Courier New', monospace;
  --font-body: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif;
  --font-mono: 'JetBrains Mono', 'Courier New', monospace;
}
```

### Step 3: Apply the grid background to body

```css
body {
  background-color: var(--bp-deep);
  color: var(--bp-text-secondary);
  font-family: var(--font-body);
  background-image:
    linear-gradient(rgba(42,74,107,0.3) 1px, transparent 1px),
    linear-gradient(90deg, rgba(42,74,107,0.3) 1px, transparent 1px),
    linear-gradient(rgba(42,74,107,0.15) 1px, transparent 1px),
    linear-gradient(90deg, rgba(42,74,107,0.15) 1px, transparent 1px);
  background-size: 100px 100px, 100px 100px, 20px 20px, 20px 20px;
}
```
