Ejemplo

import { ThemeProvider, useTheme } from './theme_provider'

<ThemeProvider themes={allThemes} defaultTheme="dark">
  <App />
</ThemeProvider>

// Dentro de un componente:
function ThemeSwitcher() {
  const { themeName, setTheme, themes } = useTheme()
  return (
    <select value={themeName} onChange={(e) => setTheme(e.target.value)}>
      {Object.values(themes).map(t => <option key={t.name} value={t.name}>{t.label}</option>)}
    </select>
  )
}

Notas

Detecta prefers-color-scheme automáticamente. Persiste elección en localStorage. Exporta ThemeProvider (componente) y useTheme (hook).
