 *   src/Padmon.App/Styles/PadmonStyles.xaml   (page, card, text styles)
 *   src/Padmon.App/Views/ControllerDetailPage.xaml
 *   src/Padmon.App/Controls/ControllerDiagram.xaml / StickGraph.xaml
 *
 * Fluent uses Segoe UI Variable; the stack below falls back gracefully on macOS and
 * Linux while keeping the same sizes and weights.
