One [Theme][pythonnative.Theme] holds the app's design tokens: [Colors][pythonnative.Colors], [Typography][pythonnative.Typography], a [Spacing][pythonnative.Spacing] scale, and [Radii][pythonnative.Radii]. Components read it with [use_theme][pythonnative.use_theme] and derive styles from it once per theme with [use_styles][pythonnative.use_styles]. The built-in navigators draw their headers, tab bars, and drawers from the same tokens. [ThemeProvider][pythonnative.ThemeProvider] supplies a light and a dark theme and picks one from the effective color scheme; without it, [LIGHT_THEME][pythonnative.LIGHT_THEME] and [DARK_THEME][pythonnative.DARK_THEME] apply.
