# Metrics95

Geometry tokens for controls, windows, desktop items, and taskbar content.

Metrics95 is the single source for classic sizes such as bevel width, title bars, scroll thumbs, and interaction offsets.

## Use it

```swift
import Swift95

let metricTheme: Theme95 = {
  var metrics = Metrics95.classic
  metrics.titleBarHeight = 34
  metrics.scrollBarWidth = 18
  return Theme95(
    colors: .classic,
    metrics: metrics,
    fonts: .classic
  )
}()
```

## Essential behavior

**Geometry**Metrics affect rendering and layout, not only decoration.

**Interaction**Minimum thumb, line increment, and resize-handle values support usability.

**Customization**Start with .classic and change only intentional differences.
