Access theme colors as platform-agnostic JSON tokens:

import tokens from '@lgtm-hq/turbo-themes/tokens.json';

const mocha = tokens.themes['catppuccin-mocha'];
console.log(mocha.tokens.brand.primary); // "#89b4fa"

import { initTheme, wireFlavorSelector } from '@lgtm-hq/turbo-themes';

// Initialize theme system
initTheme(document, window);
wireFlavorSelector(document, window);

from turbo_themes import ThemeManager, THEMES

manager = ThemeManager()
manager.set_theme("catppuccin-mocha")
css_vars = manager.apply_theme_to_css_variables()

import TurboThemes

let mocha = ThemeRegistry.themes[.catppuccinMocha]
// Use theme colors in SwiftUI views
