o11y/frontend/stubs/next-themes.ts

// Browser stub for `next-themes`, eagerly imported by the @hanzo/ui barrel
// (`import { useTheme } from 'next-themes'`). o11y is not a Next app and drives
// its own theming (index.html boot script + hooks/useDarkMode), so this returns a
// stable dark default. A real browser cannot resolve the bare `next-themes`
// specifier, so it must resolve to this module (aliased in vite.config.ts) instead
// of being externalized — otherwise the SPA crashes at load with a blank page.
