## Background

```xml
<defs>
  <linearGradient id="bg" x1="0%" y1="0%" x2="100%" y2="100%">
    <stop offset="0%"   stop-color="#0d1117"/>
    <stop offset="50%"  stop-color="#161b22"/>
    <stop offset="100%" stop-color="#0d1117"/>
  </linearGradient>
  <!-- Ambient glow spots -->
  <radialGradient id="glow-blue" cx="30%" cy="40%" r="40%">
    <stop offset="0%" stop-color="rgba(88,166,255,0.15)"/>
    <stop offset="100%" stop-color="rgba(88,166,255,0)"/>
  </radialGradient>
  <radialGradient id="glow-purple" cx="70%" cy="60%" r="35%">
    <stop offset="0%" stop-color="rgba(188,140,255,0.12)"/>
    <stop offset="100%" stop-color="rgba(188,140,255,0)"/>
  </radialGradient>
</defs>
<rect width="960" height="600" fill="url(#bg)"/>
<rect width="960" height="600" fill="url(#glow-blue)"/>
<rect width="960" height="600" fill="url(#glow-purple)"/>
```

## Glass Card Effect

SVG cannot do real backdrop-filter, so simulate with:

```xml
<defs>
  <filter id="glass-blur">
    <feGaussianBlur in="SourceGraphic" stdDeviation="0.5"/>
  </filter>
</defs>

<!-- Glass card: layered rects -->
<!-- 1. Subtle inner shadow -->
<rect rx="12" fill="rgba(255,255,255,0.03)" stroke="none"/>
<!-- 2. Glass body -->
<rect rx="12" fill="rgba(255,255,255,0.06)"
      stroke="rgba(255,255,255,0.15)" stroke-width="1"/>
<!-- 3. Top highlight line -->
<line stroke="rgba(255,255,255,0.25)" stroke-width="1"/>
```

## Typography

```
font-family: 'Inter', -apple-system, 'SF Pro Display', 'PingFang SC', 'Microsoft YaHei', 'Microsoft JhengHei', 'SimHei', sans-serif
font-size:   14px labels, 12px sublabels, 20px hero title
font-weight: 400 normal, 600 semi-bold, 700 bold titles
```

## Gradient Text (for hero labels)

```xml
<defs>
  <linearGradient id="text-grad-blue" x1="0%" y1="0%" x2="100%" y2="0%">
    <stop offset="0%"   stop-color="#58a6ff"/>
    <stop offset="100%" stop-color="#bc8cff"/>
  </linearGradient>
</defs>
<text fill="url(#text-grad-blue)" font-weight="700" font-size="20">
  AI Pipeline
</text>
```

## Arrows

```xml
<defs>
  <marker id="arrow-blue" markerWidth="8" markerHeight="6"
          refX="7" refY="3" orient="auto">
    <polygon points="0 0, 8 3, 0 6" fill="#58a6ff"/>
  </marker>
</defs>
<!-- Slightly glowing line -->
<path stroke="#58a6ff" stroke-width="1.5" fill="none"
      opacity="0.8" marker-end="url(#arrow-blue)"/>
```

## SVG Template

```xml
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 960 600"
