## Usage Guide

### ✅ Recommended Uses

- **Web headers**: `typedialog_logo_h.svg` (animated, full color)
- **App icons**: `typedialog_icon.svg` (animated, square)
- **Favicons**: `typedialog_icon_s.svg` (static, optimized)
- **Social media**: `typedialog_logo_h_s.svg` (static PNG export)

### ⚠️ Things to Avoid

- Distorting proportions
- Changing colors arbitrarily
- Removing components
- Using below 32px without testing
- Adding effects (shadows, blurs)
- Substituting fonts

---

## Export Options

For different use cases, export SVGs as:

- **PNG**: High-resolution static image (email, social)
- **PDF**: Vector print-ready format
- **WebP**: Modern browser optimization
- **EPS**: Adobe Suite compatibility

### Favicon Generation

See `FAVICON_GENERATION.md` for step-by-step instructions on creating PNG and ICO files from the SVG source.

font-family: "Inter", -apple-system, BlinkMacSystemFont, sans-serif;
```

- **Weights**: 400 (regular), 500 (medium), 600 (semibold)

## Technical Details

### SVG Structure

```xml
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 64" fill="none">
  <defs>
    <style>
      @import url('https://fonts.googleapis.com/css2?family=Inter:wght@500&display=swap');
    </style>
  </defs>
  <!-- Path elements for bubble, brackets, cursor -->
  <!-- Text element for wordmark -->
</svg>
```

### Scalability

- **Minimum**: 16×16px (favicon, with testing)
- **Recommended minimum**: 32×32px
- **Optimal**: 64-256px
- **Maximum**: Unlimited (SVG is infinitely scalable)

### Performance

- **Small file size**: ~1.3 KB per file
- **No dependencies**: Animated versions use CSS only
- **GPU optimized**: CSS animations use hardware acceleration

---

## Accessibility

- **Color Contrast**: WCAG AA compliant
