Next.js static export

Static exports cannot rely on server-side runtime configuration. Either keep the public Mushi env vars in NEXT_PUBLIC_* or disable runtime config explicitly.

Mushi.init({
  projectId: process.env.NEXT_PUBLIC_MUSHI_PROJECT_ID!,
  apiKey: process.env.NEXT_PUBLIC_MUSHI_API_KEY!,
  apiEndpoint: process.env.NEXT_PUBLIC_MUSHI_API_ENDPOINT,
  runtimeConfig: false,
  preset: 'production-calm',
})

For local static previews, the default runtimeConfig: 'auto' skips localhost config fetches so a stopped local Supabase stack does not create self-noise or api_cascade prompts.

Use widget.anchor instead of Shadow DOM CSS injection when the exported site has sticky UI:

widget: {
  anchor: {
    bottom: 'calc(72px + env(safe-area-inset-bottom))',
    right: '16px',
  },
}
