Package and use fonts

Put font files beside your design package and declare them in dsp.json.

{
  "assets": {
    "fonts": [
      {
        "family": "Worka Sans",
        "weight": 400,
        "style": "normal",
        "path": "fonts/WorkaSans-Regular.ttf",
        "format": "ttf"
      }
    ]
  }
}

Codegen verifies the font path and emits packaged font bytes.

DesktopApp::<AppState, _>::new(App)
    .with_design_system::<AppDesignSystem>(DesignMode::Light)
    .run()

Use the generated typography tokens inside widgets. Avoid assuming a platform font exists.
